Young adults generally have the same consumer rights as other shoppers, including protection under the Consumer Rights Act 2015 when goods, services or digital content are faulty, unsafe or not as described. For faulty goods, you may have a short-term right to reject them within 30 days, while repair, replacement or a price reduction may be relevant afterwards, depending on the circumstances. Online purchases usually come with a 14-day cancellation period, although exceptions apply. Keep receipts and contact the trader first; Citizens Advice can explain your options if the dispute is not resolved.
