Audi SA just a huge disappointment

I am extremely disappointed at Audi SA worst service. A week ago my car was sent to Audi Umhlanga cause of a coolant problem. All costs ended up being 21000plus minus. This morning the car gives the same issue. This is the last Audi I purchase or advise anyone to purchase. I am awaiting the unhelpful Audi SA to contact me if I am not happy I am willing to let this car park for a while. I will address the issue with the Ombudsman(MIOSA). The very sarcastic Audi SA agent even works on my nerve asking me “what do you think should be done?”. I am sorry that’s not what I expect from a customer care agent who’s meant to be the one giving solutions. The worst part is the Audi near me(Richards Bay) has even worse service.
