How to Report Fraudulent Bank Transaction
Discovering an unauthorized bank transaction can be frightening, but acting quickly can improve the chances of protecting the remaining funds and creating a proper investigation record. In Nigeria, customers should report suspicious or fraudulent transactions to their bank through an official channel as soon as they notice them.
A fraudulent transaction can involve an unauthorized transfer, card payment, ATM withdrawal, debit, electronic payment or another transaction that the account holder did not approve.
What Counts as a Fraudulent Bank Transaction?
A fraudulent transaction is generally a transaction that was made without the account holder’s authorization or through deceptive or criminal activity. Examples include unauthorized transfers, card transactions the customer did not make and withdrawals that the account holder does not recognize.
Not every unfamiliar transaction is necessarily fraud. Some may be recurring subscriptions, merchant names that appear differently on statements, delayed transactions or payments made by an authorized family member or employee.
Check the Transaction First
Before reporting the transaction, check the date, amount and transaction description. If the transaction is unfamiliar, do not assume it is legitimate simply because the description looks familiar.
If you have access to your banking application, review the transaction history and determine whether there are other suspicious transactions.
Contact Your Bank Immediately
The first major step is to notify your bank through an official customer-service channel or branch. Tell the bank that you are reporting an unauthorized transaction.
If your card or banking credentials may have been compromised, ask the bank about appropriate protective measures. Depending on the situation, the bank may block a card, restrict certain channels or take other steps to protect the account.
Do Not Give Your PIN or OTP to Anyone
A common fraud pattern involves criminals pretending to be bank employees. They may claim that they are investigating the fraudulent transaction and ask the victim for an OTP, PIN, password or authentication code.
Do not provide these confidential credentials to someone who contacts you unexpectedly. Use the bank’s official channels instead.
Change Compromised Passwords
If you suspect that your mobile banking password or another login credential has been exposed, use the bank’s official security process to change it.
Do not use a password sent by an unknown person. Also avoid reusing the same password across banking and unrelated services.
Keep Evidence
Save transaction receipts, account statements, SMS notifications, screenshots and relevant messages. If the fraud involved a phone call, suspicious message or social-media conversation, preserve the information without continuing to interact with the suspected fraudster.
Evidence can help the bank understand how the transaction occurred and can also become important if the matter requires further investigation.
Ask for a Complaint Reference
When you report the transaction, request a complaint or case reference if the bank provides one. Record the date and time of your report and the channel used.
This helps you follow up without having to explain the entire incident from the beginning each time.
Report Multiple Transactions Separately if Necessary
If several unauthorized transactions occurred, provide the complete list. Do not mention only the largest transaction while leaving other suspicious entries unexplained.
Organize the transactions by date, amount and type. This can make the investigation easier.
What If the Fraudster Contacted You?
If the fraud resulted from a phishing message, fake customer-service call or fraudulent website, preserve the evidence. Do not click additional links or send further information.
Where appropriate, report the incident to relevant law-enforcement or cybersecurity authorities in addition to your bank.
What If the Bank Does Not Resolve the Complaint?
Start with the bank’s formal complaint process and allow the institution to investigate. If the complaint remains unresolved, ask the bank about its escalation procedure and the appropriate regulatory complaint channel.
Keep all reference numbers and correspondence because an escalation is easier when there is a documented history.
