How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Outcome

Four weeks after buying a used car that kept developing problems, even after a warranty repair, a UK buyer thought he was stuck: the dealer's 30-day return only covered up to 250 miles and he'd done about 500. ChatGPT told him about his rights under the Consumer Rights Act 2015, and he says one email later the dealer agreed to take the car back with a full refund.

ChatGPT

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Let's work out my rights for a faulty purchase and write one clear email asking for my remedy.

What I'll share as we go:
- What I bought, when, and from whom
- What's gone wrong and any repairs so far
- The seller's own return or warranty terms

Rules:
- Explain which consumer laws apply where I live, with official links.
- Separate my legal rights from the seller's own policy.
- Draft a firm, polite email citing the law and asking for a specific remedy.
- Say when I should get independent advice.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A plain summary of my rights and a ready-to-send email.

You'll know it worked when: the seller agrees in writing to a refund, repair or replacement.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
