Facebook account was hacked need help?

Okay so this morning I woke up and i saw I got a text on my phone from facebook which a security code for facebook meaning someone was trying to log in to my account. Apparently they were successful as the email to log in and the password were changed. They also changed the recovery options to where the only way is to try and get in through verifying the email which once again is not mine. When I try and get around that facebook basically says they cant verify my identity. However, my phone number is still linked to the facebook account and I'm trying to figure out if there is a way to get in using it even if its not set up anymore. I was told to email disabled@fb.com but idk. i did email them though. Like it recognizes my old password and that it was changed a few hours ago then when it asks if I made the change I say no and that I need to secure my account and then it tries to send a code to the random email the hacker is using which is obviously not mine so at this point I have no idea what to do.
