I Have Lost My TikTok Account

I am writing regarding my TikTok account with the username “Shaiyri_club” which I have been unable to access. I know the username but no longer remember the password. The account was only linked to a phone number, not to an email address, and that phone was lost in the sea. Because I no longer have that SIM card, I cannot receive the verification codes TikTok sends, and I am completely locked out of my account. My last successful login to this account was about one year ago. When I try to recover the account through the app, I am constantly sent around in the same steps without any real solution, because all options require access to the old phone number. Since I have also lost access to my previous Gmail address, I cannot use email-based recovery either. This situation is causing me serious distress, as I cannot reach an account that belongs to me. I kindly request that TikTok Support assist me with manual identity verification and then change the phone number registered to my account so that I can set a new password and regain access. My account clearly shows previous logins from my devices, and I am willing to provide any reasonable information or documents needed to prove that I am the rightful owner. I ask for urgent help and clear instructions on how I can recover my account under these circumstances.
