Complain about a shop or service
Faulty goods, refunds and unfair treatment.
First, complain to the business in writing (WhatsApp or email is fine) and keep your receipt.
If they don't fix it, you can complain to the Competition and Consumer Authority (CCA).
Keep copies of receipts, messages and photos of the problem.
