You think Hertz will honor the original price that says "rate is gauranteed" on my original reservation email?
Probably, but leave extra time since will have to stop at the counter and it will likely require manager intervention.
A few questions though:
1. How much was the reservation as originally booked?
2. How much did it go up?
3. What PC code was used on the reservation?
4. Can you tell by looking at the cost breakdown whether the PC code "fell off" the reservation?
5. Did the base price change or remain the same?
We'd probably be able to help you better if you posted the before and after price breakdown here.
