I am surprised that this method still working.
Easy finding username and password with 5BTC balance, and someone believes in that. It's so naive. The worst thing is, first he sends 0.02 and it's double naive but sending new 0.035 it is no longer naivety.
Anyway i searched and found the number of the company,but it is one with expired day.Company Number was OC393265 which is for LA CLOTHING SOLUTIONS (MIDLANDS) LLP.
it's a pity you didn't research better before sending the money. but who would remember that
