I Need TikTok to Restore Access to My Account and Videos

I am writing regarding my TikTok account “usern0230688527,” to which I lost access around April of this year. My phone number was changed, and I did not have an email address or any third‑party login linked to the account. At the moment, the only information I have is the exact username. There were more than ten videos on this account, and there are important things in it that I urgently need to recover. I contacted TikTok support from the United Kingdom, but the responses I received were not helpful and I still cannot access my account. The system only offers verification through the old phone number, which I no longer have, so I am stuck in a loop and unable to log in or reset my password. I kindly request that my access to the account “usern0230688527” be restored and that I be allowed to change the password and update my contact details so I can use secure, up‑to‑date information. I am ready to provide any further information TikTok may need to verify that I am the rightful owner of this account.
