I tried to message you but "newbies can't message you".
Regarding your post to get back your facebook account, I recommend you to
contact
CristianOff on this forum.
He is an Ethical Hacker (aka 'the good hackers who help people'). He will probably give you an agreement
to sign for you to let him attempt recover your facebook. He is a kind person so he may not charge you but
I don't guarantee that.
He helped my friend from Brazil to recover 5 Instagram business accounts from f*cking hackers for ?100
I don't think 1 account is much work for him so that's why it may be free xD
