If you think your account was disabled by mistake, you must appeal Facebook's decision.
You must cultivate your patience and wait, wait and wait. Among the millions of accounts, there are tens of thousands of people living the same situation as you. When you submitted your documents you were the last among the tens of thousands. Facebook has to examine every one of them. You must wait your turn and it may take several weeks.
