Bad customer service in a new car!!

Well we bought a brand new kwid from renault boksburg our sales person was Jaques,he service up to the buy was good but he's after market service as appalling. Doesn't answer when you message him when you call he says he will call back never did, I sorted the insurance problems out myself or else I'll still be waiting. Anyway after that which was in Dec 2021 our brakes started squealing when you brake which shouldn't as its a brand new car!! And the clutch plate had a shutter, plus the anti smash and grab started making bubbles?? Now I ask myself how this is suppose to be a new car with no problems hence that's why I bought a new car as not to have any problems for a long time. So we contact out sales person as who else hoping to get some help but to be ignored, so we contact the dealership where they give us the new sales manager nr who we contact promising high and low to sort everything out. We arrange with her to bring the car in and she will make sure we get dropped at work on time the whole nice talk guess what we get there Friday morning at 7am as prearranged but was she there NO does she answer her phone no, did anyone know about taking us to work again NO. So we decide to leave as we can't loose our jobs due to the unprofessional service of renault boksburg, as we drive out we get helped by the workshop manager a Mr kobus also promising us help the next Monday which was the 17th January 2022. So again we make our way Monday to the dealership where they a bit late but we got dropped off at work ect no worries, the problem is did any of them bother to contact us during the day to let us know what's happening, no nothing I had to phone and not once got through to the workshop manager to hear why or whats happening to the vehicle. So I contacted the sales manager where she never answers the call but eventually reply on WhatsApp just saying they done with the breaks doing the smash and grab which apparently is called llumar, when I asked what about the clutch no they will test it after the smash and grab which I think they forgot until I reminded her. Anyway they were late to fetch my hubby at work no one bothered to still contact my hubby Mr willem britz about he's vehicle what was done or why ect??? What time of service is this??? We drive the car home and the brakes are squealing worst than before the tint is still not right. When we call no answer to not the sales manager or Jaques the man we trusted that we bought a car that won't give us problems. This is not on hey really we feel we bought a new car thinking we made the best deal possible we feel like canceling the deal and going to another dealership totally different as we are very unhappy.
