I consider that Catawiki are extremely unreliable, because I have written 3 messages in due time and they only responded to the third one, although they could see in the system that I had an argument with the seller who sent us a painting with multiple holes in the paint, advertised as good. Catawiki said we did not write in time and they paid the seller. The seller had said to us that he will do what Catawiki tells him to. Catawiki contact system is completely unreliable because there is no automatic confirmation of the complaint and also the complaint is not directly registered as CLAIM with legal number, we did not get any confirmation and no answer. It is their duty to protect the buyer not only the seller. As buyer I completely respected my contract, Catawiki has cashed their money - auction fees -when paying the seller, so it was in their interest to pay the seller and ignore our repeated messages / claims. As long as there was no settling of the claim with the seller and they could see this in their system, they were not normally supposed to pay him.
