TikTok Won't Let Me Recover My Old Account Despite My Ownership Claim

I have a TikTok account with the username “amongusfan2008” that I created around 2019, and I have been unable to access it for years because I forgot the password. I no longer have access to the email address or phone number that were linked to the account, and there are no other recovery options connected. I contacted TikTok support and explained the situation, but I was told that there is not enough information to verify that the account belongs to me. Since I have been locked out for such a long time and cannot use the usual recovery methods, I am stuck and unable to regain access on my own. I kindly request that my case be reviewed again and that I be given an alternative way to verify my identity and recover my account “amongusfan2008”, such as answering detailed questions about the account or another manual verification method. I would like to continue using this account instead of losing it permanently.
