Bank complaint letter for South Africa

When a bank gets something wrong, a phone call to the call centre rarely fixes it — and it leaves no paper trail. A written complaint does two things a call cannot: it creates a dated record of exactly what you asked for, and it forces the bank to route your matter through a formal complaints process with a reference number. That record is also what the National Financial Ombud will ask for if you have to escalate.

When to send a bank complaint letter

A formal letter is the right next step once the call centre has failed you or the amount is significant. Common situations include:

• Unauthorised or disputed debit orders — a deduction you never mandated, or one that continued after you cancelled it.
• Incorrect or undisclosed fees — charges that don't match your pricing, duplicate fees, or penalties applied in error.
• Failed or refused reversals — a payment sent to the wrong account, a double debit, or a transaction the bank won't reverse.
• Card fraud and phishing losses — unauthorised card or app transactions where you want the bank to investigate and refund.
• Home loan, vehicle finance and credit disputes — statement errors, misallocated payments, or a settlement figure that doesn't add up.
• Poor service or ignored queries — a complaint that has gone unanswered for weeks despite follow-ups.

Which South African law applies

You don't need to cite chapter and verse yourself — LetterUp selects and references the appropriate provisions for your specific complaint so the letter reads as considered and professional, not emotional.

What to include in your letter

A bank complaint that gets actioned is specific and unemotional. Yours should contain:

• Your full name and account number (never your PIN or full card number).
• The exact date, amount and reference of each disputed transaction.
• A short, factual account of what went wrong and what you have already done about it.
• A clear remedy — the reversal, refund or correction you want.
• A firm but reasonable deadline (10 business days is standard) and a note that you will escalate to the National Financial Ombud if unresolved.

Where to escalate if they ignore you

If the bank doesn't resolve your complaint fairly, you have a free, independent route — but you must exhaust the bank's own process first.

Your LetterUp complaint gives the Ombud exactly the dated, itemised record they expect to see.
