Totally horrendous, the tracking doesn't seem to work, you sell an item, it does not track, you email them and provide them with evidence that you posted, you get the spam AI reply (a lot like the positive reviews here, totally nondescript nonsense) and they tell you the company has 48 to scan, they scanned it right in front of me, now for the 3rd time an item with Royal Mail is on the way, but on Vestiaire the tracking does not work, the customer service (if you want to call it that) doesn't even react, so my items go to the buyer, then get cancelled as apparently I didn't send them (despite sending them and having the receipt, but customer support doesn't do ANYTHING), I get downgraded for "not sending" what a joke, the "buyer" gets an item for free and a refund, all because they use Royal Mail who has tracking problems and their freaking bots don't don react to people sending in evidence that they have posted. They do need closing down! Total scam and rip off
