Bad Car Sales service at WBC- Horrible attitude and hostile conduct

I wanted to buy two cars from them, one cash and the other financed. I got the financed approved and I had my selected car that I had paid a holding deposit on. I got insurance approved and paid insurance before collection. on arrival the car is no longer available. I opted to buy another car with platinum sticker, a promise of excellent state of the car, but before I take delivery, I noted that the dashboard leather was pinned down by staplers. I immediately rejected the car, Manager promised to sort the matter out at no cost to me. I took delivery on the car, to date, 3 months later, the car is still not sorted, as we picked more and more additional problems. The car has been with WBC service provider, no follow up by customer care, no feedback. The attitude of the customer care agent, Sihle Olayi and her Manager, very horrible!
