Worst car rental experience ever!!! The car broke down on the side of the highway, and Hertz did nothing. They said they'd send a tow truck but it never showed up. We kept calling them and they kept putting us on hold and leaving us on hold. They left us broken down on the side of the highway for over 3 hours. I finally had to call CAA to get us towed back to Hertz at the airport. A few days later they charged my credit card an extra $50 for nothing!!! DO NOT rent a car from Hertz at the Calgary airport. What a horrible experience!
