Game center; iPad required a reset password; now a code?

Game center; iPad required a reset password, now I'm blocked as it wants a 'code'; and won't let me recreate a new id for the game center. I am OLD, HOW do I fix this garbage??? (Ps: I waited FOUR days for Apple to send PERMISSION for me to change my password, which they accepted and yet, huh? Everything runs on my OLD password, so WTF?)
