Reply to a complaint about you without getting defensive

Help me reply to a complaint about me.

Their complaint: [paste]
What I accept: [details]
What I see differently (facts only): [details]
Outcome I can offer: [optional]
Channel: [email / message]

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

Then:
1. A calm sendable reply.
2. Counter-attacks removed, with why.
3. A private vent I will not send.
4. When to take it offline or get advice instead.

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.
