Don't believe the positive reviews about him, they've been written by newbies with just 1 posts and of course they're fake users created by him! He got a bank transfer and kept saying he hadn't got the money, then when I said his bank confirmed the transfer had reached his account he stopped answering and disappeared.
If what you are saying is true, best course of action is to head over to
Scam Accusations board and create the topic using
Scam Report Format. Just make sure to provide as much evidence as possible, like screenshots of the conversation, proof of payment etc.
Ask the user why he's not answering anymore when evidence of his theft has come out, I have all Telegram screenshots. Should I waste time in reporting him after having been scammed?
