i have experienced it too and unfortunately until now my facebook account is locked because i no longer have the mobile number for it has been a long time since ive used it. i can log in to my fb account but i cant proceed inside the account sad to say. my identification cards wont work because the name on my facebook account is actually nit the same on my id. remember that in the previous years, fb has been very famous that some people had gone with so many different names and multiple accounts so yeah thats my problem too. i guess all my important memories, photos, conversation and information will just be there stocked in that account forever :-( if there will be any solution then iwould say that thats miracle.
