i rented a minivan from hertz for 2 months. i used the prepay option. total is about 2800. i did it for a tzedakah organization and they are not happy with the price. i already have it for a week. even if i change the return date the price doesnt change. (besides for taxes/fees). any ideas how i can get out of the rental so i can make a new one for a better price? thanks
