Not able to reset password because hacker changed everything


New Email
I use 2 accounts in hotmail and one of them I only use occasionally for facebook.
My facebook was hacked today, and my email- and when I went to reset my password, the email they were going to send the new password to, is one I do not recognize. So the hacker changed everything.

So I tried to do the other option and fill in the little questionnaire- but a lot of the questions I didnt know (what was the last subject line...ect) because I only use the account for facebook and actually do not use it often.

I am not sure what to do!
Is there a different way to verify my information? or any way to delete the account.
