Just make a new account (redownload game) and use the in game help chat. What is stopping you from using in ganne help chat? Also, next time link your account to Facebook or ATA account so that it is easy to recover.
A picture or a better explanation of what goes wrong would definetely help. If you have linked your FB account, go to Menu -> Extras -> Sign in with Facebook. Help chat is the one that says help. I guess you probably know that already, but just to make sure.
