Sold guitar for $ 3500 to an American who questions to me through Yahoo! Auctions. He said "The payment finished in my Lloyds Bank account." And I recieved emai from "Lloyds Bank". They asked to deposit $ 1000 as "International Fast bank commission taxes"at Bitcoin. I paid. After that, "Japan international comittance will not approve if it is not more than $ 11500, so please add the additional amount with Bitcoin. That’s 100% OK," and the deposit was unavoidably requested. Addirionally After that, I received a message saying that “Vat payment final fee is $ 6000, so total $ 23500 will be deposited”, and I thought it was suspicious. I lost about $13000 and my loving guiter.(All emails from Lloyds are stored)
