I Need TikTok Lite to Update My Phone Number and Restore Access

I am having a problem accessing my TikTok Lite account and I would like your urgent help. My account username is @user1414801487054 (Endy nongqotho). I lost the phone number linked to this account a few hours ago, and since then I have not been able to log in. This account is very important to me because I have many things on it that I value and I do not want to lose it. I would like you to help me change the phone number linked to this account so that I can log in again and continue using it safely. I kindly request that you assist me with verifying my identity by another method and updating the phone number on my TikTok Lite account @user1414801487054 as soon as possible, so I do not lose access to it.
