How much was stolen? You left him feedback stating $800 USD?
Ok, I will go straight to the thing... My friends from the site ( game ) told me to this shit, I know, It is my thing if I do it or not, but I can't say NO. It's just my nature and I can't do anything with it. I already contacted the support about this thing and you can chargeback without any problem. I'm sorry for this and I also 100% accept the negative trust, because what I did was really wrong.
I suggest you try to change your nature or it may come back to bite you one day.
