I just tried booking a car in MAD using B999000. The website gave me an error, saying "The Avis Worldwide Discount (AWD) number you have entered cannot be found in our records."

I called the 800#, and when I went to reserve, the phone agent said that the computer told her that the AWD # is for Chairmen only (whatever that means), and that my name didn't match the list of people who can use this AWD.
Has that ever happened to anybody?
Have other people had luck using AWD B999000 internationally w/no problems?
