Telegram Account Hijacked and No Response From Customer Support

On November 8, my Telegram account appears to have been hacked and since then I have not been able to log in. When I try to access my account, the application asks me to enter a code for a number that does not belong to me, so I cannot complete the login process and I am completely locked out of my own account. I tried to solve the situation by contacting Telegram support and the available help channels, but I did not receive any response or help. At the moment I have no access to my account or my messages. I request that my Telegram account be recovered and returned to my control as soon as possible. I also ask you to secure my account, remove any unauthorized access, and inform me about the steps taken regarding this incident.
