Facebook Help is Useless

I have had the worst experience with some random Hacker. The sad part is I tried to notify Facebook of what was happening but they did absolutely nothing to assist me and now I'm locked out of my own account. I have tried every method of trying to contact Facebook about this but nothing works as the person has now removed all my contact information from the account so I can't even request a password reset anymore. Paul4Asa was my username and the email address linked it was ***

Do assist me please
