IC Nissan pathetic service

I have a Nissan Qashqai and around March 2019, when I started to brake, the steering wheel would nearly shudder out of my hands. I took it to IC Nissan Roodepoort and was told that the front break disks would have to be skimmed as I has aftermarket brake pads on it caused the damage. Really? I paid for them to skim and replace the brake pads. A few weeks later I experienced the same problem and took it back and was told they had to skim it again as there was some rift on the one and they don't know the cause. A few weeks later the same thing started happening again. This time I was told that they over-skimmed the disks and that it had to be replaced. I asked them to check why this kept on happening as there seemed to be some play on the front right wheel. Once again the drove up and down and eventually came back to me and said that the lower control arms need to be replaced as that was the cause of the play on the wheel as well. They quoted me and I had to take a loan as the warranty did not pay the full amount. The lower control arms, disks and brake pads had to be replaced. So in February 2020 I had the money and had everything replaced. During the lockdown the same thing started happening again! So I take it back in June and speak to the service manager Susan. Booked the car in again and this time I was told there is play on the wheel and the steering rack needs to be replaced at R27000! IC Nissan must pay for this as they made the wrong diagnosis. When I went to see the service manager I was told that she was to emotional to speak to me and every time I go there she is busy and never gets back to me. Pathetic.
