Very unpleasant experience. I booked for the first time a rental car through CarFlexi. The local Hertz could not provide the car class and offered to cancel at no charge.
A few weeks after I discovered CarFlexi charged me. I asked for a refund but they wouldn't take responsibility and gave all sorts of excuses why not.
Big f' scam company, stay away!
Booked with Rentalcars- excellent service and never let me down
