I don’t have any transaction in this account with them, but my other bidding account does. I Bid and win a Buddha pendant from them, after waiting for more than a month a finally received it and it’s totally different item, size are 1cm different color of the jade is different, I contact them all they say is they make a size mistake and refuse to returned the item. And I have to pay 6000usd for a piece of craft. Don’t bid with them.
