Telegram Two-Step Verification Not Enough to Recover My Account

I am writing because I can no longer access my Telegram account and I urgently need it to be reactivated. My account is registered with the phone number +94 7576667**, but I no longer have access to this phone number. I am trying to log in from my phone, and each time the system insists on sending a verification code to this old number, which I cannot receive anymore. I have a backup email address registered to my account and I also have two-step verification enabled, and I clearly remember my password, but I am still not given any option to log in using my email or my password alone. I have tried all options presented in the app and followed the instructions on the screen, including the “one‑time SMS fee” verification step, but I remain locked out of my account. I am completely stuck in the same verification loop with the old phone number and cannot reach my messages or contacts. I request that my Telegram account linked to the number +94 7576667** be reactivated and that you provide me with a way to log in again without using the old phone number. I am ready to provide any additional verification information you may require so that I can securely regain access to my account as soon as possible.
