Ran into a serious security glitch on eBay

[yellowperil]

Long, complicated story, but basically I put a router up for auction on 4/28 and two buyers attempted to use Buy It Now at roughly the same time (didn't know it at the time). One of the buyers' IDs (call him A) showed up as the winner, yet the other buyer ("B") was allowed to check out and send payment via PayPal 15 minutes after the auction ended. What's even worse, B's info somehow showed up in A's PayPal account. I don't know WTF is going on until eBay e-mails me back but suffice to say it is some major sh!t. Just a heads up
