Why this answer
What actually matters
- Consumer service law can make certain information binding where the consumer relied on it.
- Proof can be harder without a written record, but difficulty proving something is not the same as it being legally irrelevant.
- Call recordings, contemporaneous notes and follow-up emails may help.
What you could say
Keep the response tied to the actual rule.
Evidence
What to have beside you
- Quote, order, specification or scope of work
- Messages and call notes showing what was promised
- Photos, reports or other evidence of defective performance
- Terms relied on by the trader and when they were supplied
If they still refuse
Move the dispute forward.
- Define the contractual promise or statutory service standard that you say was not met.
- Ask for the remedy that follows from that problem rather than simply demanding compensation.
- Use formal complaint, ADR or court routes according to the sector and amount involved.
