I don't have a problem with Avis doing that. But maybe they should allow you to de-link your AWD code from your Wizard number. I try to make reservations and blank out the corporate code, and it auto defaults to the corporate code. The only way I can make reservations on Avis is without using a Wizard number. I haven't figured out how to de-link my old corporation and AWD code from my wizard number.
So, the least time I thought I successfully did it, when I went to the rental and saw the receipt, the AWD code was on there. Am I just going to have to get a new Wizard number (I have had this one for at least 25 years.....)?
