Sorry to hear about this...
Just FWIW, I have had dozens of dealings on the B/S/T (both buying and selling) and have never encountered an issue. It's still a great place to buy, sell and/or trade.
Hope this doesn't sour people on using it... I guess I'm just trying to say that this is a pretty rare occurance- and is the exception, rather than the "norm".
Regardless, I hope you're able to get this resolved. I've enjoyed our problem-free transactions, and appreciate all of your recent business
