We have never disqualified a bidder, but the auction site does allow it. Don't give up. Seller probably had a previous Non-Pay bidder, got mixed with you.
Their lack of customer support is staggering. I will never use that sight to buy any thing again. You cannot talk to any body on the phone. And they don't care about you the customer. They don't want or need my business. Run away from them far far far away.
