Can't Get Access To My TikTok Account

I am writing regarding my TikTok account with the username @iz_ang_ie, which I have been unable to access since around 12 January 2026. The phone number linked to this account is 0816838303. Despite many attempts, I still cannot log in or recover access, and I am very worried about losing this account permanently. I have tried using the passkey and standard login methods, but they do not work. I also attempted to reset the password and tried third-party login options, but these methods also failed. I no longer have access to my old phone, which makes the process even more difficult. I even deleted the app and reinstalled it, yet the problem continued. When I try to recover the account, the system says it cannot find it, but when I search on TikTok, I can still see my profile and username, which shows that the account still exists. I have also contacted TikTok support and filled out the recovery forms. However, the process requires me to provide the exact date when I created the account, and I genuinely do not remember that information. Because of this, I am stuck and unable to complete the recovery steps, even though I am the real owner of the account. I have not made any purchases or payments on this account, so I cannot use payment history as a verification method either. I kindly request that you manually verify my identity using alternative methods and restore my access to the account @iz_ang_ie. I am ready to provide any additional information or documents needed to confirm that I am the rightful owner of this account. I would appreciate your support in helping me regain access as soon as possible.
