Adverts are misleading, my son (15 years old) signed up once I found out they have already taken 3 payments (£9.99 each time) from his account and haven’t refunded or replied dispute me advising he is a minor and therefore any contract is non enforceable. He didn’t receive the free pair advertised and only one pair for 3 payments so even the deal is a scam. Enforcement to recover losses I will take up on his behalf if they don’t refund all payments this month
