TikTok Won't Let Me Update My Phone Number

I am a TikTok user from Islamabad, Pakistan and I am unable to access my account because the phone number linked to it will soon be deactivated. My TikTok username is “raja__ahmad__1” and the linked number is 031166650**. This number is no longer usable for login and I am at risk of permanently losing access to my account. I tried to resolve this issue through TikTok’s support and in‑app options, but nothing has worked so far and I still cannot recover my account or update the phone number. I would like my TikTok account “raja__ahmad__1” to be recovered and the login phone number to be updated to my new contact information so that I can use my account again without losing my data and followers. I request that this issue be reviewed urgently and that my account be restored with a new, accessible phone number as soon as possible.
