To dispute an FNB debit order, log a dispute through the FNB Banking App, Online Banking, Cellphone Banking, USSD on *120*321#, a branch, or Telephone Banking. If you act within 40 calendar days of the transaction, FNB reverses the money into your account immediately. After 40 days the case moves to a manual investigation, and the bank must communicate an outcome within 40 business days.1FNB. Debit Order Disputes | Services
When You Can Dispute
A dispute is not a way to undo a purchase you regret or a subscription you forgot to cancel with the service provider. It exists for collections where something went wrong between the mandate and the money leaving your account. FNB recognises four grounds:
- You never authorised the debit order, including fraudulent debits set up without your knowledge.
- You authorised a debit order, but the amount or the date does not match what you agreed to.
- You instructed the service provider to cancel the debit order, but collections continued.
- You placed a stop payment through FNB, but the collection still went through.
If you authenticated the debit order yourself with your card and PIN, or the collection matches what you approved, FNB will not process the dispute. In that case, take it up with the service provider.1FNB. Debit Order Disputes | Services
DebiCheck debit orders sit outside the dispute process when they are working correctly. Because you approve the mandate details in advance and the bank validates every collection against those stored parameters, a DebiCheck debit that matches your approval cannot be disputed. If you receive a DebiCheck authorisation request for something you did not initiate, reject it in the app rather than approving and disputing later.2Payment Association of South Africa. Debit Orders
Which Channel to Use
The right channel depends on the size and age of the disputed transaction.
The Banking App, Online Banking, Cellphone Banking, and USSD (*120*321#) handle debit orders of R200 or less that are within 40 calendar days of the transaction date. Log in, open the debit order or transaction history for the affected account, select the transaction, choose the dispute reason, and confirm the amount and date.1FNB. Debit Order Disputes | Services
For debit orders above R200, or any dispute older than 40 calendar days, use a branch or call Telephone Banking on the number on the back of your bank card. Private Banking clients can go through their Private Advisor. A branch consultant works through the form with you, verifies the details against the bank’s records, and submits it on your behalf.1FNB. Debit Order Disputes | Services
Whichever channel you use, you should receive a reference number when the dispute is logged. Save it. That number is your proof of submission and the identifier FNB uses to track the case.
What to Have Ready
Open your bank statement before you start. You need the exact rand amount and the precise date the debit came off your account, copied from the transaction history rather than guessed. A mismatch between what you enter and what the bank’s records show can cause the dispute to fail.
Know which of the four dispute reasons fits your situation. If you pick the wrong one and the investigation turns up a valid mandate for the category you chose, the dispute can be rejected outright. “Amount was wrong” and “never authorised at all” are different categories with different investigation paths.
Keep any supporting documents accessible: a cancellation email you sent to the service provider, confirmation of a previous stop payment, or any correspondence about the mandate. These matter most for disputes older than 40 days, when FNB has to investigate whether a valid agreement exists between you and the collector.1FNB. Debit Order Disputes | Services If the debit involved fraud rather than a billing dispute, that is a separate track — call the FNB Fraud Department on 087 575 9444 and be ready to provide an affidavit, SAPS case details, and proof of the transaction.3FNB.

Timing, Fees, and What Happens Next
Within 40 calendar days of the transaction, FNB reverses the funds into your account immediately when you submit the dispute. There is no waiting period.1FNB. Debit Order Disputes | Services
Older than 40 calendar days, FNB opens an investigation to verify whether a valid agreement exists between you and the collecting company. The bank will communicate the outcome within 40 business days from the date you submitted the dispute.1FNB. Debit Order Disputes | Services
FNB may charge a fee for processing the dispute, and the fee applies whether the dispute succeeds or fails. The amount varies by account type, so check the current pricing guide.1FNB. Debit Order Disputes | Services
Follow the Dispute With a Stop Payment
A dispute reverses a collection that has already happened. A stop payment blocks the next one. If an unauthorised debit order has hit your account, dispute the collection first, then place a stop payment so the same collector cannot pull money again next month. A stop payment on its own will not recover money already taken.1FNB. Debit Order Disputes | Services
Stop payments come with their own rules. You must place the stop at least five business days before the debit order’s scheduled collection date, or that month’s collection may still go through. Stop payments expire after 12 months, so a long-running instruction needs renewal. And if the service provider changes the abbreviated name, reference, or amount on the debit order, the stop payment may not catch the new version.1FNB. Debit Order Disputes | Services
The 60-Day Window From 13 April 2026
The dispute window across all South African banks, including FNB, changes on 13 April 2026. The Payment Association of South Africa, the South African Reserve Bank, and the Financial Sector Conduct Authority are standardising the dispute period for all debit order types — EFT, Registered Mandate, and DebiCheck — at 60 days from the transaction date.4Nedbank. Dispute a Debit Order FAQs
Under the old system, dispute windows could stretch up to 365 days depending on the debit order type, and cases older than 40 days could still be handled manually through a branch. From 13 April 2026, that manual process for transactions older than 40 days is eliminated. EFT debits will be immediately reversible within the 60-day window, and once 60 days pass, the transaction can no longer be disputed at all. Check your statements regularly and act quickly when something looks wrong.
If FNB Rejects the Dispute
Ask FNB why the dispute failed. Common reasons are the wrong dispute category, a DebiCheck transaction that matched an authenticated mandate, or a filing that fell outside the dispute window. If the rejection came from a factual error, you may be able to refile with corrected information.
If FNB’s internal process has run its course and you remain unsatisfied, escalate to the National Financial Ombud Scheme (NFO). The NFO offers free, independent dispute resolution between consumers and participating financial institutions, but only after you have already lodged the complaint with FNB and given the bank a chance to respond. Submit the NFO’s application form from their website, or contact them on 0860 800 900 or at info@nfosa.co.za, and include the bank’s name, your account number, a factual summary, and copies of the correspondence.5National Financial Ombud Scheme South Africa.
