FS cannot reset password, and says to contact the local help center.
I "am" the local help center, and do not know how to help this user. He has tried to reset his password via email and mobile phone, but gets the same answer. He has several user names, and has tried them all. I suggested that he create a new account, but the system tells him this account might already exist (despite completely different user name/password), and directs him to log in and then the same line of action.
