Recover Lost TikTok Account Without Phone Number

I have an old TikTok account with the username @pro.chix that I can no longer access. I lost access to this account around February–March 2025. I can no longer use the SIM card that was linked to the account, I cannot access the email, and I have also forgotten the password, so I am completely locked out. The email address I wrote earlier (amaramuti***[email protected]) is not currently connected to my TikTok account, so I cannot use it for recovery. Because of this, I am unable to receive any verification codes or password reset links and I cannot log in, even though this is my own account. I have already contacted TikTok Support via in‑app chat and clearly explained that I lost my SIM card and cannot access the old email, but the support assistant told me they cannot help me recover the account through email or other social media accounts. Despite this, I am still the owner of the account and I do not want to lose it permanently. I kindly request that you help me recover access to my TikTok account by verifying my identity through alternative methods and updating the contact details so that I can log in again.
