Write a firm personal complaint that asks for a clear fix

Write a personal complaint letter or email.

What went wrong: [facts, dates]
What I paid / ordered: [details without card numbers]
What I want: [refund / repair / apology — specific]
Deadline for reply: [date]
Evidence I have: [list]
Vent (will not send): [optional]

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

Then:
1. A firm sendable complaint with clear ask and deadline.
2. Subject line.
3. Vent lines removed, with why.
4. When to use Citizens Advice consumer guidance next.

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. Give a sendable version and, when I've pasted a vent, a one-line note on what you left out and why. This is help with wording, not legal advice. UK English.
