What Bank Transactions Can You Dispute in Cambodia?
- Unauthorised transactions — charges, transfers, or withdrawals you did not initiate
- Duplicate charges — same transaction charged twice
- Wrong amount — transaction processed for an incorrect amount
- Failed transfer not refunded — money left your account but did not arrive at the destination
- ATM error — cash not dispensed but account debited
- Unauthorised fees — charges not disclosed in your account terms
- Interest calculation errors — interest charged incorrectly on loans or deposits
- Card fraud — purchases made without your knowledge or authorisation
Step 1: Internal Bank Complaint
- Contact your bank immediately — phone hotline, in-app chat, or branch visit. For card fraud, request an immediate card freeze.
- Request a complaint reference number — NBC requires all licensed banks to issue formal complaint reference numbers. Do not accept a verbal promise without a reference number.
- Submit in writing — email your complaint to the bank’s official customer service email with full transaction details, your account number, and what you expect as resolution.
- Gather all evidence — see evidence checklist below.
- Allow 15 business days — NBC’s minimum standard for bank response. Most banks respond within 5–10 days for straightforward cases.
- Document all communication — keep emails, chat transcripts, and names of staff you spoke with.
Step 2: NBC Escalation (If Bank Fails to Resolve)
If your bank has not resolved the dispute within 15 business days, or if you disagree with their decision, escalate to the NBC.

FAQ: How to Dispute a Bank Transaction in Cambodia 2026
Q: What is the first step to dispute a bank transaction in Cambodia?
Contact your bank immediately — by phone hotline, in-app chat, or branch visit — and formally raise a complaint. Request a complaint reference number, which all NBC-licensed banks must provide. Submit the complaint in writing to the bank’s official email with full details of the disputed transaction, your account number, and the resolution you are seeking.
Q: How long does a bank have to resolve my complaint in Cambodia?
Under the NBC’s Financial Consumer Protection Framework, NBC-licensed banks must respond to formal complaints within 15 business days. If the bank does not respond within this period or does not resolve the matter satisfactorily, you may escalate directly to the NBC through its consumer protection portal at nbc.org.kh.
Q: How do I escalate a bank dispute to the NBC in Cambodia?
Submit your complaint via the NBC’s online portal at nbc.org.kh, or visit NBC headquarters at No. 22-24 Norodom Blvd, Phnom Penh in person. Bring your National ID or passport, your bank account details, the bank’s complaint reference number, and all supporting evidence. NBC acknowledges complaints within 5 business days and typically completes investigations within 30 to 60 business days.
Q: Can foreigners dispute bank transactions through the NBC in Cambodia?
Yes. NBC consumer protection applies equally to all customers of NBC-licensed institutions regardless of nationality. Foreigners holding accounts at ABA Bank, ACLEDA, Canadia, or any other NBC-licensed bank have the same right to file complaints with the NBC as Cambodian nationals. Bring your passport rather than a national ID when filing in person.
Q: What can the NBC do if I win my bank dispute?
The NBC can order the bank to refund the disputed amount, reverse unauthorised fees, pay compensation for demonstrable losses, or take regulatory action including fines. The NBC’s powers are strongest for clear regulatory violations — unauthorised charges, processing errors, and failure to follow consumer protection rules. Disputes about pricing or product terms the bank disclosed in your agreement are harder to win.
Q: My ATM didn’t give me money but my account was debited. What do I do?
This is one of the most common bank disputes in Cambodia. Go to the bank branch immediately after the failed ATM transaction — the same day if possible. Report the failed transaction with the ATM location, date, time, and amount. Request they initiate a terminal dispute. The bank must reconcile the ATM till and, if confirmed, credit your account — typically within 3 to 7 business days. Keep your ATM card and any receipt the machine may have printed.
Q: I see a transaction on my account I don’t recognise. Could it be fraud?
Possibly. Before assuming fraud, check if it could be a pending transaction from a recent purchase, a subscription renewal you forgot about, or a merchant using a different trading name than the store name. If it remains unrecognised after checking, contact your bank immediately to freeze your card and initiate a fraud investigation. The earlier you report suspected fraud, the stronger your case for a refund.
Q: Do I need a lawyer to dispute a bank transaction in Cambodia?
No. For standard consumer disputes — unauthorised fees, failed transactions, wrong amounts — you do not need a lawyer to file with the bank or the NBC. The NBC process is designed for ordinary consumers. A lawyer may be beneficial for complex disputes involving large amounts, property-related banking issues, or situations where the bank has caused significant demonstrable financial loss and you are seeking legal remedies beyond NBC’s administrative powers.
Q: Can I dispute a Bakong transfer that went to the wrong account?
Bakong transfers in Cambodia are generally irreversible once completed — they process instantly and the receiving bank controls the funds upon receipt. If you sent money to the wrong account via Bakong, contact your bank immediately to initiate a recall request. Your bank can contact the receiving bank and request voluntary return of the funds. However, if the recipient refuses to return the money, recovery requires legal action. This is why double-checking recipient account details before sending is critical.
Q: What is the NBC’s Financial Consumer Protection Framework?
The NBC’s Financial Consumer Protection Framework is a regulatory structure requiring all NBC-licensed institutions to treat customers fairly, provide clear product information, maintain complaint procedures, and respond to disputes within defined timeframes. It was introduced to protect Cambodian bank customers from unfair practices and gives the NBC authority to investigate, mediate, and impose penalties on banks that violate consumer protection standards.
