Unable to report a post that harasses me and my family

So recently a group of people have been targeting me and my family and have made threats directly on the post but in the native language. Everyone finds it violent except for TikTok as they haven’t still taken it down even after multiple report attempts.

I’m genuinely concerned because that person has used my family pictures(without my consent ) and make it a public threat.

What’s the next best way I can take this post down?
