Start by identifying the exact failure, then complain in writing to the institution that controlled that step. In an Indian IPO using ASBA or UPI-ASBA, a bank error can involve bid submission, UPI-mandate approval, blocking, debit, or release of funds. The remedy depends on that stage. Some failures have a prescribed payment—most notably a qualifying delay in unblocking—while a rejected bid or missed investment opportunity does not automatically create a right to expected IPO profits.
Preserve the application and mandate records, ask the responsible bank or intermediary to explain the failure and calculate any applicable compensation, and escalate an unresolved securities-market complaint through SEBI’s SCORES platform. A banking-service dispute may instead require the applicable RBI grievance route.

What ASBA and UPI-ASBA actually do
ASBA means Application Supported by Blocked Amount. The application amount is placed on hold in your bank account rather than transferred immediately to the issuer. SEBI describes the process this way: “In ASBA, money to the extent of price of the shares for which the investor has applied, is blocked, but it remains in their account till allotment.” If shares are allotted, the required amount is debited; if you receive no shares, the blocked money is released without a conventional refund.

The bid information and UPI details move through the IPO processing chain to a sponsor bank, which sends a mandate request to the UPI app or bank. You must approve the mandate within the permitted window, after which the amount is blocked in the bank account linked to that UPI ID. Retail individual investors can apply through UPI for up to ₹5 lakh per transaction, according to SEBI’s investor guidance.

Several entities therefore touch one application:
- Intermediary: the broker, bank or other application channel that accepts and uploads the bid.
- Stock exchange: receives bid data and processes the issue records.
- Sponsor bank: sends the UPI mandate and coordinates blocking instructions.
- SCSB (Self-Certified Syndicate Bank): the bank authorised to accept ASBA applications and block funds.
- Registrar and issuer: maintain allotment records and communicate the outcome.
- Your bank or UPI provider: presents the mandate and controls the account-side approval, block and release events.
Because responsibility is divided, “the bank made an error” is not precise enough for a compensation claim. First establish where the transaction stopped and which institution controlled that step.
Which IPO error occurred?
Write a short chronology before contacting anyone. Record when you submitted the bid, when the issue closed, when a mandate arrived, when you approved it, and when funds were blocked, debited or released. Then classify the problem.
Bid not submitted or not uploaded
The intermediary may have failed to transmit the application, or the bid may not have reached the exchange before the deadline. A late application, a technical error on the customer side, or a failed upload can produce the same visible result: no valid bid number or no entry in the final application status. Ask the intermediary for the exchange upload timestamp and the reason the bid was excluded.

UPI mandate never arrived
A missing mandate can result from an incorrect UPI ID, a sponsor-bank or UPI-system failure, or an intermediary error. Keep the screen showing the submitted UPI ID and the time you placed the bid. Do not assume that a successful broker order screen means the payment instruction was successfully generated.
Mandate arrived but was not approved
An unapproved mandate within the permitted period commonly causes rejection. If you did not open or approve the request in time, that is different from a bank or sponsor-bank failure that prevented a valid mandate from being delivered or processed. The institution’s logs should show whether the request was sent, delivered and approved.
Correct mandate but no block, wrong block or duplicate block
Compare the bid amount with your bank statement and the mandate record. A bank may have failed to place the required hold, blocked an incorrect amount, or placed more than one hold. Record each transaction reference and the exact start and end time of every block.
Allotment debit or release problem
After allotment, the amount due for the shares should be debited. For a non-allotment or partial allotment, the unused block should be released. A release that is late, incomplete or duplicated is a different claim from a bid that was never considered.

SCSB failure kept the bid from consideration
If the application was not considered because of an SCSB failure, the specific offer-document disclosure cited by SEBI gives the bidder three months from listing to seek redress from that SCSB. That disclosure states that the SCSB should resolve the complaint within 15 days; further delay attracts interest at 15% per annum or another rate prescribed by applicable law.
When compensation is prescribed
Compensation is not an automatic payment for every rejected IPO application. The clearest measurable rule concerns a delayed release of blocked money.
Delayed unblocking after the offer closes
For a qualifying delay of more than two working days from the bid or offer closing date, the cited SEBI-hosted offer-document disclosure provides compensation at the higher of ₹100 per day or 15% per annum of the bid amount, calculated for the period beyond the two-working-day threshold. The intermediary responsible for the delay bears the liability.
The clock matters. Count working days from the relevant bid or offer closing date, identify the date on which the block was actually removed, and calculate only the excess delay. Do not count calendar days automatically, and do not use the bid-submission date unless the applicable issue rule says that date starts the clock.

The SEBI-hosted 2025 disclosure lists compensation mechanisms for several UPI-ASBA situations, including cancelled, withdrawn or deleted applications with delayed unblocking; duplicate blocking; excess blocking; delayed release after non-allotment or partial allotment; and delayed complaint resolution. The published approach generally uses ₹100 per day or 15% per annum, whichever is higher, but the qualifying amount and starting point differ by category. Apply the formula for the category that matches your records; never borrow the delayed-unblock formula for a different event without checking the relevant issue document and current SEBI framework.
Bid omitted because of SCSB failure
For a bid not considered because of an SCSB failure, use the separate redress window: contact the concerned SCSB within three months of listing. The cited disclosure gives the SCSB 15 days to resolve the complaint and provides interest for delay beyond that period at 15% per annum or the rate required by applicable law.
What is not an automatic award
The official material does not establish a blanket entitlement to the profit you might have made if the IPO application had succeeded. A share price may rise, fall or remain unchanged, and an expected allotment is never guaranteed. Keep two issues separate:
- Prescribed compensation: a regulatory amount triggered by a defined blocking, unblocking or processing failure.
- Opportunity-loss or damages claim: a fact-specific assertion that requires proof of responsibility, causation and a legal basis; it is not automatically payable merely because the stock later traded above the issue price.
Evidence to gather before making a claim
A strong complaint lets the institution match your account, bid, mandate and bank logs. Assemble one folder containing:
- IPO name, issue closing date and listing date.
- Application or bid number, PAN and relevant demat identifiers.
- The route used: broker, bank, web portal, mobile app, ASBA form or UPI-ASBA.
- Name of the SCSB, sponsor bank, intermediary and the bank account used for ASBA.
- UPI ID and the Unique Mandate Number.
- Mandate-request, delivery and approval timestamps.
- Screenshots or an exact transcription of error messages.
- SMS and email alerts showing submission, rejection, approval, blocking, debit or release.
- Bank statements showing every block, debit and reversal, with dates and amounts.
- Allotment status and the registrar or exchange response.
- Copies of earlier complaints, ticket numbers and replies.
Redact passwords, UPI PINs, one-time passwords, card details and other authentication secrets. Transaction references and timestamps are useful; credentials are not. Keep the original files and submit copies or exports that can be opened by the recipient.
How to complain to the responsible institution
1. Choose the first recipient by failure stage
Use the bank’s IPO or ASBA grievance channel, or its designated nodal officer, when the account-side block or release is at issue. For a UPI application, copy the institution that controlled the failed step: the intermediary for a missing upload, the sponsor bank for a mandate-generation problem, the bank holding the ASBA account for blocking or release, and the registrar when the dispute concerns allotment records. If the first recipient says another entity is responsible, ask for a written transfer or a precise explanation rather than starting over without a record.
2. Describe facts, not conclusions
State the issue, closing date, amount, timestamps and the result. For example, explain that a ₹40,000 block remained after the applicable release date, rather than simply writing “the bank cheated me.” A neutral chronology makes it easier to identify the responsible log and prevents a customer-side missed approval from being confused with an institutional failure.
3. Request specific actions
Ask the institution to:
- Confirm the exact stage at which the application failed.
- Name the entity responsible for that stage.
- Provide the relevant transaction or mandate timestamps.
- Release any amount still blocked.
- Identify the applicable SEBI compensation category.
- Show the calculation period, rate, daily amount and total payment.
- State the expected payment or unblocking date.
SEBI’s investor guidance says, “The concerned company or intermediary shall facilitate your complaint redressal.” Give the recipient a reasonable opportunity to investigate, but retain proof of the submission date.

A phone explanation is difficult to escalate. Request a response that states whether the complaint is accepted, rejected or transferred, with the reason and the records relied on. If the institution says the issue was caused by insufficient funds, an unapproved mandate or late submission, ask it to identify the timestamp supporting that conclusion.
How to calculate a delayed-unblocking claim
Use a worksheet with these fields: bid amount, offer closing date, two-working-day threshold date, actual release date, qualifying delayed days, ₹100-per-day amount, 15%-per-annum amount and the higher figure.
Rank #4
- Confirm the closing date shown in the issue documents.
- Count two working days from that date according to the applicable rule.
- Record the date and time the bank actually removed the block.
- Count only the working days or days specified by the relevant compensation provision after the threshold.
- Compute the daily alternative: qualifying days multiplied by ₹100.
- Compute the annual-rate alternative using the bid amount, 15% per annum and the qualifying period required by the rule.
- Request payment of whichever permitted amount is higher, and show your arithmetic.
For illustration, do not treat a numerical example as a promise that every case uses the same day-count convention. If the applicable rule produced 4 qualifying days, the ₹100-per-day alternative would be ₹400. The 15%-per-annum alternative would still need to be prorated over the qualifying period using the method specified for that category. Ask the institution to state its day-count method if the two calculations differ.
Escalating an unresolved securities-market complaint
Use SCORES after approaching the entity
SEBI describes SCORES as “an online grievance redressal facilitation platform provided by SEBI.” The normal sequence is to complain first to the concerned company or intermediary, then use SCORES if the response is absent or inadequate. Attach the original complaint, delivery proof, the institution’s response, the bid and mandate records, bank statement entries and your requested remedy.
Write the relief in measurable terms: release ₹X still blocked; pay the applicable delayed-unblocking compensation for the qualifying period; or investigate and compensate the SCSB failure under the issue-specific provision. Avoid asking SCORES to award an unsupported forecast of future share-price gains.
Know the 30-day action-report period
SEBI’s investor grievance guidance states that the regulated entity must file an Action Taken Report within 30 days of receiving the SCORES complaint. This is a response and reporting deadline, not a guarantee that SEBI will award the amount you requested. Read the entity’s action report, challenge factual errors through the available response mechanism, and preserve the complete case record.
When a banking grievance route may fit better
Some disputes concern a bank service rather than a securities-market intermediary—for example, an account block or release issue that falls outside SEBI’s jurisdiction. The SCORES FAQ directs investors to the appropriate RBI or Banking Ombudsman channel for such bank-only matters. Check the jurisdiction before filing, and include the bank’s earlier complaint reference because banking grievance systems generally expect prior contact with the bank.

Common reasons a claim fails
Blaming the wrong institution
A broker screen, sponsor-bank message and account statement can each show a different part of the process. Send the complaint to the party that controlled the failed event and copy the other relevant participants when responsibility is uncertain.

Confusing release with compensation
Getting your blocked money back restores access to your funds; it does not necessarily pay the separate compensation due for a qualifying delay. State both requests separately.

Using the wrong clock
Compensation provisions can start at offer close, listing, a complaint date or another defined event. Identify the trigger in the applicable issue document or current SEBI framework before calculating.
Claiming expected IPO profits as a fixed amount
A later market price is not proof that an allotment would have occurred or that the investor would have sold at that price. Ask first for the prescribed remedy and present any additional damages argument only with evidence of causation and a legal basis.
Sending secrets with the complaint
UPI PINs, OTPs and passwords cannot prove that a mandate failed and create an account-security risk. Use transaction IDs, timestamps and statements instead.
A practical complaint format
Use a clear subject such as “IPO ASBA/UPI application—request for investigation, unblocking and applicable compensation.” In the body, include:
- Your name, contact details and the bank or intermediary account identifier in a secure, approved format.
- IPO name, application number, bid amount, closing date and listing date.
- UPI ID, Unique Mandate Number and all relevant timestamps.
- A short chronology of submission, mandate, approval, block, allotment and release.
- The exact error and the institution you believe controlled that stage.
- The records attached.
- The remedy requested: release, explanation, category-specific compensation and payment date.
- A request for a ticket number and written response.
Keep the language factual and avoid including authentication data. If you later file on SCORES, upload the same chronology and the institution’s response so the escalation record is complete.
Decision checklist before escalation
- Do you know whether the failure was submission, mandate, blocking, debit or release?
- Have you identified the intermediary, sponsor bank, SCSB or bank that controlled that step?
- Do your records show the bid amount and every relevant timestamp?
- Was the block delayed beyond two working days after offer close, or does another UPI compensation category fit?
- If an SCSB failure prevented consideration, are you still within three months of listing?
- Have you complained to the institution in writing and kept proof?
- Are you requesting a defined regulatory remedy rather than assuming lost profits?
- Is the unresolved respondent regulated for a securities complaint, or is an RBI banking route more appropriate?
What outcome to expect
The strongest claim is narrow and documented: identify the failed stage, show that the institution controlled it, apply the correct trigger and calculation, and request release or compensation under the matching rule. A bank may reject a claim when the evidence shows an unapproved mandate, insufficient funds, missing customer confirmation or a late bid rather than institutional processing failure. Conversely, a delayed or duplicate block supported by bank records gives you a concrete basis to demand the applicable payment.
If the first complaint does not resolve the issue, preserve the complete paper trail and escalate through the channel that matches the respondent. That approach protects the prescribed compensation claim without overstating an uncertain opportunity-loss claim.
