Common examples include:
- Unexpected service charges or SMS alerts.
- Debits from online subscriptions you didn’t authorize.
- Charges for failed transactions.
- Withdrawals by scammers or hackers.
These deductions can come from different sources your bank, third-party apps, or fraudsters who gained access to your details.

Why do unknown bank deductions happen in Nigeria?
Before you learn how to stop them, it’s important to understand why unauthorized bank deductions happen. Some of the main reasons include:
- Automatic service charges: Some banks charge maintenance fees, card fees, or alert fees every month.
- Linked apps and subscriptions: If you link your account or card to mobile apps, betting platforms, or streaming services, they can automatically renew payments.
- Fraud and scams: Hackers can steal your card or account details through phishing messages, fake websites, or ATMs.
- Hidden bank charges: Some banks deduct small fees without explaining them clearly.
- Account compromise: Sharing your account details with someone or using weak passwords can allow unauthorized access.
Now that you know the causes, let’s see what you can do to stop unknown bank debits and unauthorized deductions in Nigeria.
How to check for unauthorized deductions
Before taking any action, confirm the exact deductions on your account. Here’s how to check properly:
- Review your bank statement: You can print or download your statement from the bank app or visit your branch. Go through each transaction carefully.
- Check your SMS and email alerts: Sometimes, unauthorized debits show up in your alerts even if they don’t appear in your transaction list immediately.
- Use your bank app: Many banks now have a “spend analyzer” or “transaction history” option where you can see all charges.
- Compare transaction times: Look for deductions made at odd hours or from unfamiliar merchants.
If you notice any strange deductions, take note of the date, time, and amount. You’ll need these details when reporting.
How to stop unknown bank debits and unauthorized deductions in Nigeria
Here are the practical steps to take when you notice unwanted charges on your account.
1. Contact your bank immediately
The first and most important step is to call or visit your bank as soon as you notice an unknown debit.
- Go to the nearest bank branch or contact customer care using the official phone number on your bank’s website.
- Provide details of the transaction — the date, amount, and type of deduction.
- Ask for an investigation or transaction dispute form.
- The bank is required to investigate and reverse wrongful charges within a few days if proven.
Don’t delay. The earlier you report, the faster the issue is resolved.
2. Block your ATM card or account (if you suspect fraud)
If the deduction looks suspicious, for example, from an online store or location you didn’t visit, you should block your ATM card or freeze your account immediately.
You can do this using:
- Your bank’s mobile app (many have “block card” or “deactivate account” options).
- USSD codes like *966*911# (for Zenith), *894*911# (for First Bank), *737*51*74# (for GTBank), or your bank’s equivalent
- By calling your bank’s customer care line.
This prevents further withdrawals while the issue is being investigated.
3. unlink suspicious apps and websites
If you’ve linked your bank card to apps, online stores, or digital wallets, these platforms can sometimes auto-debit your account without warning.
Go through your linked services and cancel any you don’t recognize or no longer use. For example:
- Streaming platforms like Netflix or Spotify.
- Betting sites or online shopping platforms.
- Loan apps or fintech wallets.
To unlink your card:
- Open your mobile app or website account settings.
- Select “payment methods” or “linked accounts.”
- Remove your bank card or account from the list.
This step alone can stop future unauthorized deductions.
4. Set transaction alerts and limits
To protect yourself, make sure you receive alerts for every transaction. You can also set daily limits for transfers and payments.
- Activate SMS and email alerts for all transactions.
- Set low daily limits on your debit card or mobile banking app.
- Turn on two-factor authentication (2FA) where available.
That way, if someone tries to take money from your account, you’ll know instantly and can act fast.
5. Change your banking passwords and PINs
Sometimes, unauthorized debits happen because your account details have been exposed. Change all your PINs and passwords immediately if you suspect any fraud.
Here’s what to do:
- Change your mobile app password and ATM PIN.
- Use strong passwords with letters, numbers, and symbols.
- Never share your passwords or OTP (One-Time Password) with anyone, not even a bank staff.
Banks will never ask you to share these details on the phone or through email. If anyone does, it’s a scam.
6. Report unresolved deductions to CBN or FCCPC
If your bank refuses to refund an unauthorized deduction or delays for too long, you can report to higher authorities.
You can contact:
- Central Bank of Nigeria (CBN): Send a complaint to cbn.gov.ng or email cpd@cbn.gov.ng.
- Federal Competition and Consumer Protection Commission (FCCPC): Visit their website fccpc.gov.ng to file a complaint.
Attach proof like screenshots, receipts, and communication with your bank. These agencies ensure that banks take responsibility for customers’ lost funds.
How to prevent future unauthorized deductions
It’s better to prevent these issues than to fix them. Follow these safety tips to avoid losing money again.
1. Avoid sharing your card details online
Don’t save your card number or CVV on websites or apps unless they are trusted and secure. Fraudsters often create fake sites to steal card details.
Always look for “https” in the website address; it means the site is safe. If not, leave immediately.
2. Don’t click on suspicious links or messages
Many fraudsters send fake bank alerts or emails asking you to “update your account.” These are called phishing messages.
Never click on links or download attachments from unknown sources. Always confirm any bank message directly from your official bank app or branch.
3. Use a dedicated card for online payments
If you often shop or pay bills online, use a separate debit card or virtual card for such transactions.
That way, even if the card gets compromised, your main savings remain safe.
4. Monitor your bank account regularly
Make it a habit to check your account at least once every week. The earlier you detect an issue, the easier it is to fix.
Use your bank mobile app or USSD code to view your last few transactions. If you notice any strange activity, report it right away.
5. Educate yourself and others
Many Nigerians lose money simply because they don’t understand how digital banking works. Stay informed. Read about fraud prevention, and share this knowledge with your friends and family, especially elderly people who are new to online banking.
What to do if the money was withdrawn by a scammer
If you realize your account has been hacked or scammed:
- Immediately block your account using your bank’s USSD code or app.
- Call your bank’s customer care to report the incident and provide all details.
- Ask for a transaction reversal and a written report.
- File a police report if necessary, especially for large amounts.
The faster you act, the higher the chance of recovering your money.
