Information to include
Start with the exact problem: debited but not credited, successful but not received, pending transfer, duplicate debit, wrong transfer or delayed reversal.
List facts in chronological order. The bank should understand the transaction without reading long emotional paragraphs.
Attach only safe evidence. Do not include PIN, password, OTP, token code or full card security details.
If you have already contacted customer care, include the date, channel, staff name if known and ticket number. This shows the complaint history clearly.
- Name and contact
- Bank and account affected
- Amount
- Date and time
- Session ID or reference
- Recipient details
- Complaint ticket
Simple structure
Use a subject line such as Complaint on Failed Transfer of N50,000 on 21 June 2026.
Then write what happened, what evidence you attached, when you first complained and what you want: reversal, credit confirmation, trace result or written explanation.
If escalating, mention the bank complaint reference and the date you reported it.
Close with your phone number and email, then keep a copy of the submitted complaint. If you submit in branch, ask for stamped acknowledgement or a ticket.
Tone and follow-up
Keep the tone firm and factual. Threats and insults make the complaint harder to process.
Send through official bank email, branch, in-app support or complaint channel and save acknowledgement.
If there is no response, escalate with the same facts plus proof that the bank received the first complaint.
For business payments, attach the invoice, receipt or order record so the bank understands why the delayed transfer matters.
