PSA: My Telegram account is no longer under my control. 

Not sure the person is malicious or if @koodo just handed over my number to someone else but don’t interact with @/Kuushoo on telegram.

I don’t even know why service providers abroad can’t just assign completely new numbers.

Stay safe and secure online! It's concerning when accounts get compromised. Hopefully, you can regain control soon. Perhaps reaching out to @koodo for more information on how this happened could help prevent similar incidents in the future.
