I had a reservation for Brisbane in July via the Hertz discount on my Aeroplan Platinum card. I discovered that I was overpaying slightly as the booking kept reverting to the higher prepaid rate. I tried calling but after the agent had me on hold for 15+ minutes I hung up. Some of the other car rates were $15,$20,$25/day higher for the prepaid rate which makes no sense, should it not be the OTHER way round????
My wife has a regular Platinum card so I used her account to get Avis preferred.
I got a group P car for $30 less/day. Avis GPS is $5 cheaper/day. And NO prepay. I will NEVER ever consider Hertz again.
There were other issues with Hertz too, 1hr+ wasted on phone calls.
