OP if you have been scammed by that user, use the
proper format of a scam accusation and post it in the proper section which will be here -
https://bitcointalk.org/index.php?board=83.0Provide the proper proofs and see what can be done. If the proofs are solid then the account can be given a flag to warn others. Just caling someone a liar will not work here.
Also not telegram messages screenshots because those are easily manipulated. But lets see anyway.
Best if you move this thread to scam accusations and edit the first post with proof.
