Something like this is difficult to parse through, because the PM they sent you was very undescriptive. "Being in Contact on Telegram" doesn't help me confirm that this particular user that you produced messages with; additionally I don't see any dates on the messages or the PM verification.

It would be easier to navigate this accusation if you provided direct links to the accused profile. I highly suggest only dealing with an escrow, unless there is extraordinary circumstances. More information on escrow guidelines can be found here: https://bitcointalk.org/index.php?topic=133931.0
