My Telegram Account Hacked

My Telegram account has been hacked and I have lost access to it. I am from India and the account was registered to my phone number, but I am no longer receiving any OTPs or login codes, which makes me believe that the attacker has taken over my account and changed the security settings. I urgently request that my hacked Telegram account be disabled for the unauthorized person and restored back to my phone number so that I can use it again safely. I am very worried because I cannot log in and I am afraid the hacker might misuse my profile, chats or contacts. Please review my situation as soon as possible, secure my account, and help me recover access to it on my own device.
