Facebook Hacked Email Changed and Helpless to Retrieve Back

Hello,
I am experiencing a very big problem. My facebook account was hacked 3 months ago and I have tried a lot but nothing helped me out.
The problemis that my Facebook is hacked and the email adddress and password is also changed. Its just my username which is not changed.
When I go to the hacked account page of Facebook is asked me to give an information so I put my username and then it located to my account. Then I clicked Continue so it brought me to the page where it says send the password reset link to your email ***@***. BUT the main problem is that is NOT my email but the hackers one. And there is NO other option available to recover my account, no new email option, no securty answer option at all and no phone number option also.
Please help me out in retrieving my account. I will be very grateful to you.
I am not a native English speaker so please ignore my mistakes.
Thankyou
