I rented a car via CarFlexi web site. I received the car in the airport in Romania from a rental car company called InterRent. I purchased via CarFlexi web site "Excess Damage Protection" insurance. Part of the overall payment was payed to CarFlexi in their web site, and the rest should be paid at InterRent desk on the day I take the car.
To my surprise, InterRent charged me with a much higher amount than agreed in the contract with CarFlexi. They did not agree to deliver the car at the price agreed with CarFlexi. According to InterRent this is the price of the car, and it does not include any insurance in addition to what I purchased thru CarFlexi.
I didn't have a choice but to pay and take the car.
When I came back home I contacted CarFlexi. They shake off any responsibility from their side, and did not agree to refund me on the excess amount I paid. They say that I purchased additional insurance at InterRent desk, which I didn't. They said I had to contact them right away, but they don't give you any phone number, and as a tourist who has just landed I didn't even have a local sim card to call them at this point of time.
In short, if you don't want to be cheated, you better avoid any business with CarFlexi
