MY FRIEND’S ACCOUNT IS HACKED ON FB, AND WE CAN’T GET IT BACK! WHAT SHOULD WE DO?

[Cornelia hale Ritland]

Unfortunately, my friend's account was hacked by someone kinda looks professional
The hacker has changed the password, and the email which my friend used to login with it.

beside before her account get hacked, few months ago FB stopped to email her on Hotmail, and FB required to put a new email instead of the old one, so that's why she never received on her Hotmail that the password and email was changed.

She already submit request that her account was hacked and nothing happened.
She submit another request that she doesn't use fb, and she sent photo of her ID, so with this request she can shut down her account, and nothing happened.

On fb help center she followed all the instruction of my account was hacked but none of this was helpful, already nothing happened.

We decided to report her account as fake account, so we can shut it down and it didn't got disabled.
Her sister spoke with this hacker but he blocked her sister.

This is truly frustrating, we've done whatever is possible and nothing work.
