TikTok Account Locked Due To An Unreachable Phone Number, Request Help

For more than a year I have been unable to recover my TikTok account, even though I have been trying to follow the normal recovery steps. The confirmation code for login and recovery is always sent to an old phone number that is damaged and no longer accessible, so I cannot see or use the code. Because of the damaged phone and contact, I have no way to receive the SMS or confirmation code that TikTok requires, and the process does not offer me any alternative way to verify my identity or update my number. As a result, my original account has effectively been locked and I cannot access it at all. I request that my access to this original TikTok account be restored by allowing an alternative verification method or by updating the contact details after you verify my identity in another way. I would like TikTok to assist me directly so I can safely regain control of my account.
