TikTok Doesn't Allow Me To Verify Myself Connected, Old Email And Number

I am writing regarding my TikTok account, which I suddenly lost access to two days ago in the U.S. When I try to log in, the verification code is sent to an old phone number that I no longer use or have access to, so I cannot complete the login process. I have already tried the available recovery options, including the “Can’t access this phone number” and email recovery steps, but they do not work and I am still unable to access my account. I also tried to find a way to reach support through the app and website, but I have not been able to resolve the issue. I kindly request that my identity be verified manually and that access to my TikTok account be restored, or that you help me update my phone number through an alternative verification method. I am ready to provide any necessary documents or information to confirm that I am the rightful owner of the account.
