Well this is a tough situati9on YOU are in, as the ONLY two things you can use to recover your account @https://www.facebook.com/login/identify?ctx=recover&lwv=110&ars=royal_blue_bar
is the mobile number or email.
There is nothing anyone can do!
These accounts are so important and everyone posts there entire life time on them, and they have no real idea of what they are doing! So important!!!
