Personally feeling so bad to see that continuously this scammer is committing farudulent activities and we are getting scam accusations against the same person on a regular basis. Everytime we are giving advices to check someone's trust area before making any deal but unfortunately you guys don’t feel it necessary.
Already this user have multiple negative trusts and active flag on his account but i wonder how did you missed that thing. It was your own responsibility to check his profile before sending the payment or using trusted escrow service. It is to notify you that this scammer is already on

Sorry to say that you did all mistakes by your own and got scammed. Please don't make the same mistake again otherwise they will play the same game with you again and again.
