Have you contacted the provider yet? http://ccm.net/faq/6940-my-facebook-account-has-been-disabled
How long have you waited. It does not happen over night, and it takes a while, if you have made THEM aware of the situation.
For the future, never create an account on a mobile device, but do it at a desktop. Your recovery times are much quicker, and much easier, as confirmation is the same every time, unlike mobile connections. The more points of entry you have, the harder it is for THEM to confirm YOU ARE THE ACCOUNT HOLDER!
Let us know how long it has been since you first made them aware.
I have said it once, I will say it again. IT!
