Locked out of Facebook

I have been locked out of my Facebook account for a couple of months. Each time I try to log in it says it has been locked for security reasons. It either asks me to have a code sent to my OLD phone number or enter the last 6 digits of my credit card. I can't get the code obviously and I'm not giving them my card number especially since I haven't used it to begin with. Is there some other way cause I have friends that won't add me on my new account and some of the games I played were linked to my Facebook and I don't want to have to start all over again.
