The Consumer Rights Act 2015 applies across the UK, including Manchester, and generally requires goods, services and digital content to be as described, fit for purpose and of satisfactory quality. If a purchase does not meet these standards, you may be entitled to a repair, replacement, price reduction or refund, depending on the circumstances and how long ago you bought it. Complain to the trader first, keep your receipt and record the problem and any responses. For further guidance, contact Citizens Advice or check GOV.UK; a solicitor can advise on more complex disputes.
