After a long flight there was no at the airport to meet us. After many phones calls a courier turned up in a van about 45 mins after we were waiting to take us somewhere else. When we got to the office of sixt that were provding the car they told us we had no insurance and had to 360euros on insurance. Tired after a long flight and 2 small children we tried to argue the point but we ended up paying it too argue the point on the return of the car. When we returned the car they shrugged and said that the broker rentalcars.com do not give them information and to take it up as a complaint. I have done this both to rental cars and with sixt and enither are willing to accept blame and issue a refund for either the insurance we had taken out at £110 or the one paid at the airport. In either case we will never use SIXT or rentalcars.com. we left completely ripped off.
