Disgusted at the way I was treated

I am Beyond disgusted and shocked at the way I was treated at Mahindra Benoni on Friday, 18/12/20. On the Tuesday I went to trade in my vehicle for something else. I was offered a price for my trade in vehicle and finance was approved. On Thursday I signed all the paper work and they told me to collect the new car on Friday morning. I went back Friday morning to collect the car. While I was checking the vehicle, lights, breaks etc, the manager told some guy to take my trade in vehicle for a test drive. This man damaged my trade in car on the test drive. When he got back, the manager was screaming at me that the is damaged and how can he take this as a trade in. He refused to take the vehicle because it was damaged. His one sales person told him the car was not like that on Tuesday or Thursday. He wouldn’t listen and treated me like I was some kind of an animal. He called the deal off and told me to leave. I said this man must be liable for the damaged caused to my car, he said no and refused to give me his details. I am appalled by his behaviour towards me and I will be taking this further because I am sitting with a vehicle that is damaged and I need to have fixed and it was not my doing. I am disgusted and extremely upset about this!!!
