I reserved a "Pay at the Counter" car and noticed I was charged at the day of the reservation. Carrentals said they don't know what the charge is about, refused to refund me, and told me to talk to the car supplier. When I arrived to pick up the car, the supplier said they don't see the previous charge either and demanded I pay again for the car. I did, under the assumption it'll get sorted out later. Then the supplier provided me with a very low-end manual transmission car, while I ordered a high-end automatic car. I contacted Carrentals to resolve the issue but they did nothing and I ended up having to use that car during my whole vacation, which was a nightmare. Before even picking up the car, I sensed something was wrong and asked Carrentals to double-check everything's ok with the reservation and that I will be receiving the exact car I ordered, and they confirmed I will. Apparently they didn't. After my vacation, I contacted Carrentals numerous times and haven't been able to get a refund for my double charge nor for the fact I received an inferior, barely-driveable manual car. They simply don't care.
