We rented a car from Sixt in November 2016. We drove from California to Arizona and noticed the out of state mileage charge once we had already been in Arizona for a couple of days. When we made the reservation, we made sure to check that it was unlimited miles.
We dropped the car off and got our final invoice a few days later for the rental price that was shown when we made the booking.
Its now February 2017 and Sixt have charged me an additional $1004.50 for out of state mileage.
Do I have any other options other than rolling over and paying?
