I made a reservation over the phone for a location near my location where I dropped off my car for repair. I received a rental confimation by email. I did receive a call back from this Enterprise location and was told they do not have any cars available. I was told they would contact the next closest location and have them call me. I was never called back and called the location but the phone was never answered. I found an Avis rental that answered and they were exceptional in handling my rental needs. I needed a rental again a few weeks later and the same thing happened. I got a rental confirmation and got a call back saying they didn't have any cars available. I asked if there was problems with the reservation system and they told me yes there is, there is no inventory search when reservations are made.
