Under the Consumer Rights Act 2015, you may be entitled to a refund if goods are faulty, not as described or unsuitable for their purpose, but you should first complain to the retailer and give them a chance to resolve the problem. You may have a short-term right to reject goods within 30 days; afterwards, repair or replacement may usually be the first remedy. Keep receipts, photographs, messages and details of your losses, and send a clear letter before claim. If the retailer still refuses, you can consider a small claim, following the relevant process for England and Wales, Scotland or Northern Ireland; check GOV.UK or seek advice from a solicitor regulated by the SRA.
