Horrible service. Won a beautiful mineral specimen. Paid the seller a lot of money. Item supposedly shipped September 7, the seller sends me a message a few weeks later saying item is lost in the mail and how would I like to handle this. I said refund me in full please. They say that they have issued refund supposedly and that it is up to the auction site to handle it from that point. I have waited an additional 2 weeks for the refund to show up and it hasn’t. Catawiki or the seller closed the message box for the listing so I cannot even contact the seller anymore. I appear to be out a bunch of money and what I purchased is lost. This is my first experience with this website, I cannot afford to flush money down the toilet but that is exactly what happened here. I am extremely sad and frustrated.
