I echo what DireWolfM14 said.
The username he was using on telegram is @oasis190 and to add to that, my guess from what I have observed so far is the OP is trying to give some false sense of trust based on his previous trades(trust farming) so he can impersonate the escrow without too much suspicion, e.g. (I have traded with him before there no need for me to check my shit).
a good practice to avoid falling for this is simply asking for a confirmation from the escrow here on the forum!
If what you are saying is true, I urge you to create a topic in the Scam Accusations board following the Scam Report Format
