Avis Rent A Car

I rented a car from Avis that was running when I rented it. I drove about an hour, parked at the hotel, and at the next start the car failed to even turn over. The battery was completely dead yet there were no light on, no doors open, etc. I had to wait 5 hours for roadside service to come and jump the car. The emergency technician stated that it must be a battery issue as nothing in the car was on that could have caused the issue. He recommended taking the car back to Avis and letting them know that there was a battery problem. I didn't give Avis a hard time about my lost day of use yet asked them to check the battery which they said they would do and service accordingly. A month later, I got a bill from Avis for $84 charging ME for the roadside assistance that was THEIR fault. I'll never use Avis again. Use another car rental agency that won't make their battery problems something that you pay for.
