Renault Fourways warranty department

In September 2017 I purchased a second hand vehicle from this dealership. Mark my salesman gave me excellent service I must say. Yesterday my car wouldnt start so I called the dealership to ask if nyou warranty includes the battrey. And guess what? The person in the warranty department had no idea. She could not even find my vin number in her system. I then asked her what if I have a serious problem with my car which can be fixed under warranty. . Her answer was "I don't know " . Honestly this dealership employs people who "do not know" what they are doing and can not assist their customers after sales. I missed work and needed my car fixed but they simply did not know what to do or who I should call yet they're the ones who sold me the car and warranty. I had to do my own investigation to find out which company their warranty and service plans are under, and only then did I get help with. Honestly Renault Fourways please employ more competent people.
