Help Hacked Facebook – All Meta Accounts Disabled

Yesterday morning, my Facebook account was hacked. The hackers posted content that violated Community Guidelines (child porn——phy), and as a result, my account was permanently disabled despite my appeal. My Facebook right now, doesn’t exist anymore. Since my Instagram was linked to the same email, it was also disabled - and unfortunately, the hackers changed the email address, so I can't recover it myself or save my account history. I’m an artist, and have been using instagram for a decade now to get work and keep in touch in with the industry… so I NEED to recover my account. If anyone has experience with this, or knows/is someone at Meta Facebook Instagram who could help me escalate my case, I would be incredibly grateful.
