Please Help Me Back To Restore My TikTok Account

I am writing regarding my TikTok account with the username @Sheshhh_mwuahhh. My Gmail account, which was linked to this TikTok account, was hacked, and the person who gained access changed all the details of the Gmail. As a result, I no longer have any access to that email address, and I cannot log in to my TikTok account anymore. I tried using Gmail recovery, but no account was found, so I am completely unable to restore the email that was linked to my TikTok. I also contacted TikTok and used the support options for a hacked account, but I stopped trying in December because I did not receive any response or help. I kindly request that you investigate my case, restore my access to the TikTok account @Sheshhh_mwuahhh, and disconnect it from the hacked Gmail address that is currently linked to it. I am ready to provide any additional information or proof you may need to verify that I am the rightful owner of this account. I am asking for your urgent help so I can recover my account and secure it properly.
