I rented a car in Olympia, Wa. I drove home to Oregon (about 3.5 hours) and parked the car in the driveway. Two days later I planned to drive the car to an appointment (at 1pm) but noticed a huge oil spot under the car. I called roadside service. They advised me to drive the car to the nearest open Avis (1 hour away). I informed them that I would not be driving a vehicle with no oil that far. After deliberating back-and-forth for quite some time,, the representative finally agreed with me and said she would “schedule” a tow company to pick up the vehicle and send someone to my home with a replacement vehicle. I hadn’t heard from Avis and nobody showed up to pick the vehicle up by 10 o’clock that evening. So I called roadside assistance again to inquire on the ETA. The representative advised me that the roadside tow request had expired, but he would initiate another request. I received a call from the tow company at one in the morning. The dispatch let me know that they would be at my house within an hour and a half. (2:30 am). I let him know. It was way too late to come at that time. He agreed to come the next morning, which he did. I contacted Avis again the next morning and asked them to cancel my request for a vehicle exchange. The representative told me I would be responsible for all charges through the end of my contract, which was going to be four more days. I explained to him that I wanted to cancel the reservation as soon as the tow truck picked up the vehicle. I didn’t feel I was responsible for any additional charges. I made several calls to Avis within 24 hours. At no time was I ever assured that I would not have to pay additional fees for a vehicle. I didn’t have in my possession. In addition to that, I was also told that I may be responsible for the tow fees. I am still waiting on a final charge. This was my first and only experience with Avis. I will not be a returning customer.
