I purchased the services of rentalcars.com and the precharged my credit card. When i went to pick up the car at the kiosk, the attendant informed me that there would be a mandatory insurance fee of $100 (62% mark up on the original price). The attendant was apologetic and says that this frequently happens with rentalcars.com. Given the new price, i declined the service and immediately contacted rentalcars.com to cancel the service. The company sent me an email one day later saying they allowed me to cancel the service but would issue no refund. I have called several times to the company, but I could not speak with anybody with decision making power. All correspondence was very bureaucratic. There whole business model is to offer something cheap by hiding (high) fees. I would not recommend this service to anybody. It was not that much cheaper to begin with. The offer a product that has a true price very different that advertised. In the end, I was out $150 with no car rental.
