you can contact Facebook by different options such as phone mail e-mail
it will be not hard to get the account unlocked if you are sure you have done nothing wrong but do nit give your account logins to random people on the internet it will make it more difficult to get in unlocked later since it will be accessed from different ip addresses and computers why pay money if you can do it alone just try contact them.
