This is an ongoing problem, MtGox has been telling me the funds from a transaction will be refunded automatically for three months now. When I look at the address I sent my funds to it shows a $0 balance but the funds moved out of that address within a couple hours of sending it. The vendor never received the funds  MtGox I says the purchase was cancelled and will be refunded "soon". Anybody know a way to escalate this to resolve it?
