I can't log into my facebook account Print Statisti

My facebook got hacked, and I try to log in to my facebook account. When I log it to my facebook account, it asks me to enter my security code. When it sends the security code for me, I enter it, and it says please enter your phone number and You should receive a text at your mobile with your confirmation code soon.i entered it but i did't receive any massege response from facebook.
So, I just want to know what is going on, and how to I regain access to my facebook account again.
Thank you
