Awful experience. I registered on the site and bid on an auction which I won. I received an email conforming that I won at the auction and gave details how to pay the good. I transferred the funds and started waiting for further details from the seller. After receiving no follow up I wrote directly to the seller and got a mail from him informing me that the auction was a bug in the system and the item has been sold months ago!!! Immediately contacted Catawiki and submitted a claim. What was my surprise when on the next day I received an email from them that my profile is blocked??? Now the dispute continues with the support of my bank. Do not use Catawiki!!! You will be robbed!
