Respond to a card chargeback with the right evidence

Help me respond to a card chargeback.

The notice: [paste it, including the reason and deadline]
What happened: [order, delivery or service, any contact with the customer]
Proof I have: [order confirmation, delivery tracking, photos, messages, terms they agreed to]
My payment provider: [name]

First ask me up to 4 short questions. Wait for my answers.

Then:
1. The reason given, explained in plain words.
2. An evidence checklist matched to that reason, with gaps flagged.
3. A short, factual written response, in order of importance.
4. A file-naming list so the provider can follow it.
5. Two changes to stop this happening again.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.
