You really should have used a trusted middle man (escrow) to prevent this kind of thing from happening, the cost is very little and will give you great protections.
Yes, you're totally right. Lesson learned.
I know I lost my money, but I intend this thread to be a warning for other people.
I don't think I am the first to be scammed by this guy.
It's weird that I couldn't find any other accusations, taking in consideration that his account was created more than a year ago.
I have been scammed too the same way, I sent one scammer 50 USD and he told he is from https://www.changer.com/. After that he demanded another 50 USD to sent his client. This is a TREND of Scammers
