Hertz POOR service

I'm so disappointed in the service we recieve at Val de Vie Paarl Hertz, I made a booking online reservation number 13RP3S and when I went to pick up it was declined due to not having credit card and affordability, but they took 2550 for the booking confirmation. The help desk lady was very rude and had no customer service, she even said that she will call security for my wife if we don't get out out of her office. This will inconvinienance us as we also made another booking for a Bnb in Goerge for today.
