In short: For many people “reverse payment on FNB app” means a debit order dispute, not undoing a once-off EFT. FNB’s Registered Mandate FAQ says you can dispute/reverse an RM debit order on the FNB Banking App (also Online, USSD, ATM, branch, call centre). Within 60 calendar days of a successful collection, FNB says the bank will immediately reverse that debit order. This is not the same as reversing an eWallet (72-hour unused window) or cancelling PayShap/immediate payments. Confirm on FNB. Not financial advice.

App steps (FNB Registered Mandate FAQ)
- Log in to the FNB Banking App → select Accounts
- Select the account that was debited → Account Options
- Select My Debit Orders
- Select the debit order you want to dispute/reverse
- Select Dispute
- Choose a reason → Continue
- Confirm details → Confirm
- Wait for the success screen
FNB lists dispute reasons such as: not the allowed amount; not the date agreed to; not what I agreed to.
How long do you have?
For an RM debit order, FNB says the dispute for the full amount of the collection must be made within 60 calendar days from the successful collection date. After that, disputes cannot be accepted. A successful dispute inside that window: FNB says the debit order is reversed immediately.
You cannot dispute the same RM collection again if you already disputed it.
Fees (don’t trust old blog rands)
FNB’s FAQ: they do not charge you when you dispute an RM debit order on the app / USSD / online / ATM / call centre / branch. However, if the dispute is successfully processed, FNB may charge a dispute fee, and they may charge if you dispute a valid debit order. Check the current FNB pricing guide — we do not invent a rand amount here.
Stop future debit orders
Disputing one collection is not the same as stopping the next ones. FNB says after an unauthorised RM debit you can dispute the collection and then place a stop payment to block future collections. Cancelling the underlying mandate usually needs the creditor/service provider as well. Confirm stop-payment steps and fees in the app / pricing guide.
What this page is not
- eWallet sent to the wrong number: different product — see Reverse FNB eWallet (unused funds, short window).
- Once-off EFT / PayShap / Pay & Clear Now to the wrong account: not the My Debit Orders dispute button. Use FNB’s official recall / support channels; many instant rails are hard or impossible to reverse.
- DebiCheck collections may follow related but separate FAQ wording — check DebiCheck options in My Debit Orders if that is what you see.
If the app won’t let you dispute
FNB: call the number on the back of your card, or visit a branch. Other listed channels include Cellphone Banking (*120*321# → Bank → My Debit Orders), Online Banking, and ATM.
