Advantage never showed up at 7 a.m. at the desk in Tampa. Ace Rental took my reservation at 7. They got into Advantage's computer. The car's transmission started having problems half way through the drive from Tampa Airport to my destination in Ft. Myer's. I called Ace, they called back and asked if I wanted a tow truck to tow me back. I said no as the car somehow readjusted itself when I turned it off and restarted it. Then I continued on the highway, and the transmission started having trouble again. I could only go 40 in a 70 mph zone. It was dangerous. Advantage said I did not show up for my rental. I said yes, but Ace took it over. I was told that was not possible. It was. The check engine light turned on. I sat for 30 minutes on a road off of the highway. I was told people would call me. They did not. I drive 30 mph to get to my sister's house with noises under the car. I finally made it to my sister's house. Later that evening, a tow truck dropped off a different car and took that one. The man could barely drive the car up onto the truck. He has to back it up and gun it. What should have taken me 2 hrs and 10 minutes took 5.5 hours. I understand that cars have mechanical issues. But it was the lack of communication and failure to take responsibility by the staff that was the most troublesome. I am considering challenging the charge on the car with the company because of the personal danger I was in on the highway, and the stress/amount of time it took to get to Ft. Myers. Paula Coffee
