To confirm, I even sent the scammer another message saying, I wanna choose another escrow provider (from BTT, of course). He has been dead silent from then. No response.
Do you think he will ever reply yo you, he will never because his aims is to scam you and not you getting any penny from him, Telegram is a safe heaven for most scammers and what I do most times now is never to reply to any pm that coming unauthorized, since there are mostly scams.
Stop mate stop expecting any reply from the scammer, move on and be more watchful and careful.
