Ordered some cards about a month ago, followed up after two weeks. A week or so after that the seller responded with 'I've been on holiday and just got back - Royal Mail must have lost it, I'll refund etc' and then no refund or response to any messages since (The sellers account is permanently set as 'on holiday' btw.).

30 days passed, contacted Cardmarket and the refund arrived 48 hours later. However I now can't give feedback on the seller? This seems crazy I can't warn other people? Further to this, I can't buy anything else from the seller - have they blocked me?
