Last month I have purchased (or "won", since it's an auction) 8 different lots through Catawiki. I have had major issues with 2 out of 8 (an artwork was received severely damaged, in another case I have ordered a lot of wine bottles and received different bottles from a different producer). While Catawiki is clearly not directly responsible for these issues, I as appalled by the lack of support I have received from Catawiki in order to obtain redress. Filing complaints is discouraged by the company on their webpage, recommending instead to get in touch and solve the issue directly with the sellers (while at the same time Catawiki gives you only 3 days to report an issue, before they release the payment to the seller). But if sellers prove unhelpful, Catawiki will just show no interest (despite the fact they take a generous cut of the transaction!) and be of zero help. Hence I suspect that the high likelihood of fraudulent sales (2 out of 8 in my case) may not be a coincidence but rather a consequence of Catawiki's inaction when sellers fail to respect their obligations
