You made a big mistake, dude, you trusted someone who has no reputation in the forum or rank, and he has not yet been active in the forum since last month
I think op is telling a lie. Op has not yet provided any proof so I doubt there has happened any scam. The OP told s/he will provide chat history as well as the transaction ID. But about a month passed and still there is no update regarding the chat history and/or transaction history.
