Ridiculously slow and non friendly service

I visited the Durban branch yesterday to do an inspection which should take about 15 minutes, I was told they can only assist me the next day I asked if there’s a time or an appointment. I was told “No”. I came back today, first the cashier sends me on a wild goose chase for change and tells me they can only assist me at 14:00pm(because of the system) now I need to wait another 5 hours . Fine I get the exact money and pay. And then as I’m exiting on my way out there’s a couple of Dekra employees who approach me head on, on a one way road. And they start shouting inaudible things from inside the car(one male Indian with black hair and one female indian with blondish hair). I came back to confront them, he says they mistook me for one of their Uber guys and proceeds to tell me to “fix my attitude and leave”. The service here is appalling to say the least when you enter no one greets you or gives you accurate information. The signs tell you to go to the outside window for service and the window is closed. You literally park your car and people walk around you like you don’t exist. I’m extremely disappointed in the treatment here, I had to ask other customers for help as the service people just couldn’t care less. I asked for my money back and left.
