Help me reply to a customer disputing a bill.

Their message: [paste it]
The invoice: [items and amounts]
What was agreed: [quote, messages, changes]
What's fair in their complaint: [be honest]
What I could offer: [e.g. explain, adjust, nothing]

Ask me up to 2 short questions first. Wait for my answers.

Then:
1. A calm reply that thanks them, sets out what was agreed and done, and addresses each point.
2. An offer if part of their complaint is fair.
3. A clear next step for payment.
4. What to do if they still refuse.

Calm, factual, no blame. Not legal advice. UK English.
