Charged us for fuel even when the car was full!!

Rented at George, South Africa. These guys are ******! Fill up the car before return absolutely full - the car could not take any more fuel. They charged me R150 for fuel and R39 refueling charge. There is no way that we could have driven out so much fuel in 5km, where the petrol station was. They charged R500 for a full valet for a bit of sand on the floor, where a simple vacuum would have sufficed. Daylight ******* - NEVER make use of these guys!
