And if that isn't sufficient, please, please go over to BTCPOP, sign up, and find the chatbox. (On the dashboard, can't miss it.). Just go there, and ask whoever is in there what they think of "Buysomebitcoins" AKA "Balambala".

Stay safe, and stay away from this scammer. He gives a bad name to P2P.
