Major IG celeb with over 400k followers had his page removed. How does he get it back?

A pretty big celebrity hairstylist and tastemaker reached out to me because his IG page was deactivated for violating terms of service. We're pretty sure it was just flagged by kids for petty reasons. His IG page was solely used for promoting his brand and did not contain any nudity or hate speech. He had almost half a million followers when the page was closed. I'm reaching out to see if you all have a white glove support service that handle celebrity IG accounts. I've heard reports of IG users emailing IG support with a picture of their face, but IG support rarely replies back. Any help would be greatly appreciated.
