I booked a rental car in Athens for originally 30 via CarFlexi.
At the desk of GoldCar they told me the rental costs are 30 but the insurance is 120.
They never mentioned it in the billing process on the web.
I thought ok, let's be on the safe side and I payed the insurance.
However on my credit card bill I was charged additional 60 for CarFlexi and also the 120 for Goldcar. I do not understand why I was charged 60.
Do not use CarFlexi and do not use GoldCar.
It is way to complicated to understand as a tourist.
