I Can't Recover My Tiktok Account After I Deactivated it

I have been unable to log into my TikTok account for months because I no longer have access to the old phone number that is linked to it, so I cannot receive the verification codes required to sign in. Each time I try to log in, the system asks to send a code to that old number, which I cannot use anymore. The last time I was able to access my account was in August 2025. After losing access to my phone number, I contacted TikTok support and requested that my phone number be changed so I could get back into my account. However, I was told that no account could be found with the information I provided, even though I know this is my account and I have used it actively in the past. I am requesting that TikTok help me regain access to my account by updating or changing the phone number associated with it, or by offering an alternative verification method so that I can securely prove ownership and use my account again.
