Facebook complaint: disabled my personal account

My FB account was disabled due to a linked Instagram account that is not mine.

This compromises my job big time, as I center a lot on social media, to have an online presence of my business and person for 20 years. helping others better their lives, I had 1.5 followers or more, and unjustly they let a hacker destroy my life just like that.

I received several emails from FB with a password recovery code. Then when I logged in I got the account disabled message due to the linked Instagram account violating guidelines. The message told me to contact Instagram for a review. My Instagram account is not disabled and has no restrictions or notices
it says… how do I make Facebook discover this was a hacker, not me, whatever he posted to restrict me he did it on purpose as a new modality Instagram account to appeal our decision.

I don’t know who bachhophuong is… help nor did I post anything bad, on Instagram or Facebook and constantly I was reported unjustly by envious people of stuff I shared I found on the same platform, that’s not a proper way to handle this. my user name is Alejandra Mingramm Iturraran
how do I make Facebook discover this was a hacker, not me, whatever he posted to restrict me he did it on purpose is a new modality.

I already got Instagram to appeal, then I got access to Instagram again and I looked into linked accounts and there was the hacker account mentioned above mysteriously linked to mine, on Instagram. Even I appealed when I tried today to log into my Facebook account to check it says the account doesn’t exist the hacker got upset and somehow erased my Facebook account I guess cause Facebook doesn’t find it when I use the pad, what else I can do? How is it Facebook permits, someone evil steals all my effort in one second making it unreliable for trusted businesses and entrepreneurs, who want sincerely to bring good to others.
