i keep being asked to sign in and then being told my account not verified
I keep being asked to sign in and then being told my account is not verified and to go to settings to continue to signing in at settings.When I go to setting is tells me my Apple ID is locked for security reasons and to unlock I must verify my identity but direct me to a 'Forgot Apple ID or Password' which I know is already correct and asks me to set up a new password. if I do this the sequence will continue and I will be asked to do this whole process again and again and again.
iPhone 6s, iOS 9.0.2
