Soooo I have like, four items sitting in Marketplace Limbo right now, and I'm down 202L$. I've contacted all the vendors in question, and been told roughly the same thing by all of them. Since MP hasn't paid them, they have no record of the transaction. This is ridiculous, because I HAVE AN INVOICE stating precisely what was delivered and what was not. So, aside from contacting whoever the hell is in charge of MP, I have no idea what to do. And I'm kind of angry that I'm down 202L$. >_< Feeling rather shafted, Tanaleith
