I am sick of explaining everything to you guy and you keep blaming me as if i was the scammer, i am in a very bad situation and all of what you are doing is that you are seeming me that i was the scammer. I can not respond to every comment but my talk is now to the OP, give me a day or two and I will share the loss with you and will send you money you paid to that scammer back.
Why don't you reset the Telegram account by email?
You did add an email address to the Telegram, I hope?
If your account had a 2FA password on it then you should still be able to lock them out somehow during the account reset process, unless the hacker changed the password to your telegram account (I dunno, by breaking open the password manager or something?)
