If an instant loan app has taken money from your bank account without permission, contact your bank or credit union promptly through an official channel and report the specific transaction. Then establish whether you never authorized that debit or are trying to stop a repayment you previously authorized: the bank dispute and the steps for stopping future payments are different. The rules and reporting channels depend on your country, account type, and how the money was taken.
First, identify the withdrawal and secure your account
- Open your bank’s official app or website, or use the phone number on your bank card or statement, to find its fraud or dispute contact. Report the debit promptly and provide its date, amount, and statement description. Ask whether the bank can block further debits from that originator, and request a case number and written confirmation.
- Save a copy of the statement and screenshots showing the transaction. Keep the loan agreement, payment authorization, app messages, and copies of notices you send or receive.
- Check what kind of transaction it was. A debit with an app or lender name might be a scheduled loan repayment, a separate app fee, a temporary authorization hold, a debit-card payment, or an electronic transfer such as ACH. The payment method and whether you authorized it affect the process. The CFPB’s Electronic Fund Transfers FAQs describe covered transfers and explain that an unauthorized electronic fund transfer generally means someone other than the consumer initiated it without actual authority and the consumer received no benefit from it.
For US consumers, the CFPB says to notify the financial institution right away. In the scenario described on its consumer page, notice should be given no later than 60 days after the statement showing the unauthorized withdrawal. Timing can affect the bank’s investigation and your rights; see the CFPB’s guidance on unauthorized transactions and the OCC’s guidance for customers of national banks and federal savings associations.
If you never authorized the debit, dispute it with your bank
Tell the bank plainly that you did not authorize the transfer and want to report an electronic-transfer error. In the circumstances covered by CFPB guidance, the bank must begin investigating after receiving oral or written notice; it cannot require you to resolve the issue with the lender first. Follow up in writing so you have a record, and promptly provide any written confirmation the bank requests after an initial phone report.
What the US investigation timelines mean
For US consumer accounts covered by the cited guidance, a bank generally has 10 business days to investigate, or 20 business days if the account has been open for less than 30 days. If it cannot finish within that period, it generally must provide provisional credit while continuing the investigation, subject to exceptions—including a possible request for written confirmation after an initial oral report. If the bank determines an error occurred, it generally must correct it within one business day and report its findings within three business days. The general resolution period is 45 days, with specified exceptions that may extend it to 90 days. These are procedural timeframes, not a guarantee that a particular debit will be refunded.

If you authorized repayment but want future debits to stop
An ACH authorization lets a lender make electronic withdrawals from your account for scheduled payments. CFPB guidance says you can revoke that authorization. Tell the lender in writing that you revoke it, and tell your bank too; you can ask the bank for a stop-payment order even before revoking the lender’s authorization.
Ask the bank about a stop-payment order
For a stop-payment order covering the next scheduled lender debit, CFPB guidance says to give the bank at least three business days’ notice. If you first give notice orally, the bank may require written notice within 14 days. Banks commonly charge a fee for stop-payment orders. Contact the bank promptly to confirm its process and whether a fee applies. See the CFPB’s instructions for stopping electronic lender debits.
Keep the payment dispute separate from the loan dispute
Stopping automatic withdrawals does not cancel your loan agreement or erase an amount you genuinely owe. If you also dispute the loan, the amount, fees, or whether you borrowed it, raise that separately in writing. For US payday-loan authorization concerns, the CFPB identifies state regulators, state attorneys general, and its complaint process as possible escalation channels; its guidance is not a decision on the merits of an individual loan or refund claim.
If the lender keeps withdrawing money or the bank does not resolve the dispute
Ask the bank’s complaint or escalation team for a written explanation, and keep records of any new debits. If the lender continues taking payments after you revoked authorization, report each transaction to the bank and ask what options are available to block further withdrawals. For US payday-loan issues, you can consider contacting your state regulator or attorney general, or submitting a complaint to the CFPB. Customers of national banks and federal savings associations can also consult the OCC’s consumer help site; the OCC says its answers are not legal advice.
If you are in Malaysia
Bank Negara Malaysia advises customers dealing with an unauthorized transaction or withdrawal to call their bank’s 24-hour hotline or the National Scam Response Centre at 997 immediately, then lodge a police report as soon as possible. Its guidance says to report the matter to the bank even if more than 24 hours have passed. These directions apply to Malaysia; other countries have different hotlines and reporting procedures. See Bank Negara Malaysia’s guidance on unauthorised transactions or withdrawals.

| Situation | What to tell the bank | What else to do |
|---|---|---|
| You did not authorize the withdrawal | “I did not authorize this transaction. Please open an electronic-transfer error investigation.” | Report promptly, preserve records, and respond to requests for written confirmation. |
| You authorized repayment but want it to stop | Ask about a stop-payment order and explain when the next debit is scheduled. | Revoke the lender’s authorization in writing and notify the bank. Address any loan balance separately. |
| You dispute both the debit and the loan | Report the disputed transaction as an unauthorized or erroneous transfer if that is accurate. | Send a separate written dispute about the loan, balance, fees, or borrower identity. |
The CFPB sources cited here concern US consumer financial accounts and lender electronic debits; the Malaysia guidance is country-specific. None determines whether a particular app’s withdrawal was authorized, whether a loan is valid, or whether a consumer is entitled to a refund.
