Write to my bank about an error.

What's wrong: [details]
Dates and amounts as I see them: [details — no full card number]
Account reference I can share safely: [last few digits / sort of account]
What I want them to do: [fix]
Already phoned: [yes/no — outcome]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A clear sendable letter/email.
2. Subject line with reference.
3. Emotion to keep out of the official ask.
4. When to escalate using the bank's complaints process (in general terms).

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, quotes or what the other person thinks. Not financial advice. UK English.

Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.
