I can leave here our conversation so anybody can see it.
That's the first thing you should do when opening an accusation topic, show what conversation you had and show the tx, the proof of sending him the money.
It's not that's I'm doubting completely but anyone can open accusations about anyone with no proof.
Apart from that, how can you deal with a newbie account on this forum without escrow, and you've been on this forum for two years?
How much did you lose? As I'm sorry to say but nothing will change, that's a throwaway account and he will not care if it gets tagged, he will pop-up up soon with a new username and new skype id.
