Appalling customer service, really bad hire car and huge deposit

We arrived at Cape Town airport and waited for over an hour in a queue. When we asked the woman where to find the car (it is not directly outside the car hire shop but a few rows to the right), the woman screamed at us. The hire car was in awful condition - the cubbyhole fell off when we opened the passenger side and the car made funny noises. They also took an R8000 deposit, which they do not make clear when booking and is higher than other car rentals. Definitely will not be using this service again.
