Account disabled

Hello guys,

Can you please help with an issue? My instagram account has been disabled due to some violations.. I can tell you, that I haven't done anything wrong. I received mail from facebook, where they asked me to send them some info to confirm that is my own account.
They said: "Before we can help you"... we need to verify...
I've sent them my full name, instagram account and a code they've sent to me along with a selfie.
So I did that..and didn't received any news so far. Whay should I do in this case. That was my personal account with many posts and many friends and people I know.
Maybe someone reported me... who knows.. But they can verify the report...and if there is something wrong with any posts, they remove the posts...not deletation of your account. correct?
