Reply to a cancellation and keep the door open

Help me reply to a customer who's cancelled, and keep the door open.

My business: [what you do]
Their message: [paste it]
What I know about why: [details, or nothing]
Anything I could offer: [e.g. a pause instead, a different service, nothing]

If something essential is missing, ask me 1 or 2 short questions first. Wait for my answers.

Then:
1. A gracious reply that thanks them, confirms the cancellation, and makes it easy to come back.
2. One gentle question about why, if appropriate.
3. A friendly message to send in 3 months.

Warm and professional, UK English. Add a simple opt-out line to each marketing message (e.g. "Reply STOP if you'd rather not hear from me"), and remind me to message only past customers who haven't opted out; I'll check the ICO's guidance on marketing texts and emails.
