facebook team asking me to enter a phone number to access my facebook, but I did not receive a confirmation code via sms. and finally I can not use facebook.

I am very angry because in my facebook there are a lot of the jobs data. security through facebook mobile that makes the user feel uncomfortable, because too many facebook that can not be opened just because a mistake from the team facebook itself, namely WE CONFIRMATION DO NOT RECEIVE SMS! !!!
I strongly disagree with security system like this.
