Write a clear membership cancellation that creates a paper trail

Write a membership cancellation.

Organisation: [name]
Membership / account ref: [details]
Last day I want: [date]
Notice I believe I owe: [details]
Channel required if known: [email / form / recorded delivery]

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

Then:
1. A clear cancellation message.
2. What to keep as proof.
3. Softener language that accidentally keeps me subscribed — remove it.
4. A follow-up if they ignore it.

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. UK English.
