Daily *******

I was given a Courtesy car by Budget Insurance from Europcar on 22/12/2018 at the Queenstown branch. I drove the car back to Cape Town. When I'm Cape Town I noticed that the car has a problem with brakes as it was making noise when braking then I returned to Cape Town International branch, and they replaced the car but Europcar is charging me One Way Drop Off Surcharge. The Question is now how can they charge me One Way Drop Off Surcharge while the vehicle was fault? Were they expecting me to drive the car to Queenstown while is fault. I really don't understand because on the terms and condition there is nothing like that. And they should have told me by the time I exchange the car, to return the car to Queenstown.
