Be careful on monthly rentals

Be careful on monthly rentals - Hertz are snakes!! We paid R22,450 to hire a VW Kombi for a month. We had to give the vehicle back a few days early, even did a full valet before returning it and obviously filled up the fuel tank. A few days after returning it, they charged an additional R5,310 on the credit card without even having the decency to notify us. They said the charge is because we did not use it for the full month and that the terms and conditions stated that the rate can be adjusted if the duration is changed. So they probably rented the vehicle again and had the benefit of an early return but still decided to sting the previous customer.
