Sani Sixt Disappointing

Sani Sixt pricing not exactly as advertised............ Extra charges appear when you collect the vehicle. Not even Super - Super Cover from Sani Sixt covers tyres and windscreen damage ? Car only had 8000km but already signs that the cars are not well looked after. Wipers not great for the rain we encountered. And YES, there is a charge for them to fill the fuel on top of the actual fuel ! It's a car rental company, hello ! If you fill the car there is a charge to check you filled to car and suddenly the gauge you need to trust when they say the car is full, Sixt does not trust the same gauge ? Cost is much higher what I was expecting. Looks like I was legally ****med. I'm sure they will tell me ALL car rental companies **** customers this way. It does not mean it's right !
