Telegram Account Recovery Fails After Number Is Deactivated

About two years ago, my phone number changed and I closed my old line. Because that old number is no longer active, when I try to log into my Telegram account, the verification code is sent to that unused number, and I am completely unable to access my account.
This account contains conversations and photos that are very important to me. Since I absolutely have no access to my old phone number, I cannot log into my account again and I am experiencing serious hardship as a result.
I request that a solution be provided so that I can access my Telegram account without needing my old phone number, and if possible, that my account be restored and made usable again.
