He has paid through skrill, although it was risk, i accepted, and just to confirm it was legitimate transaction, and i was away.
I have already transferred him bitcoins. I dont know why negative feedback has been left.
In your profile there's another negative feedback that was posted that I think you need to settle aside from OP thats why Lauda left you a negative feedback resulting to a red paint in your profile. Better deal with it or state here why that guy accused you as a scammer and warns everyone not to deal with you. Then ask Lauda to lift the negative trust rating.
