I have been a seller on Catawiki for several months but all of a sudden, they decided to close my account and withhold ALL MY PAYMENTS until all my disputes are closed. And I only had ONE dispute but that was reason enough for them not to pay me anymore and use MY MONEY (2000 euros) as they wish. As a seller you have no chance, they have no understanding, once you sell something you never know if you will receive your payment or not. I see many sellers are unhappy so you should avoid selling your items on Catawiki, they are an organized crime group hidden behind a website.
