As i said, he got the coin and he keep the money. There is no proof that he sent it back. This means that he is to greedy and he will scam you at the first chance that will have, outside that will always re-negotiate the rate in his favor, doesn't matter if you are some old business partner. This guy is just another junk in this world and i'm very sorry that i worked so long with him, because i was 100% that this will end bad for me one day.
I had the feeling before giving him the last amazon codes, but i said, c'mon the world is not so bad as you think, but it is.
The world will fuck you at first sign of weakness, LOL.
