You should move this thread in the reputation section and also why do you post here about scam while the transaction happened in the telegram? Do you know the guy here in the forum? If yes then please include his bitcointalk.org profile here so that DT will tag him as scammer. This is the only way you can avenge your loss in the forum.

Can you write here also the BTC wallet address of the hacker. Maybe we can find him if he join on signature campaign/bounty campaign here in the forum.

That's not huge amount but in this time of pandemic. All money really matter. Sorry for your loss
