Shocking service assistance and problem with car

I bought my Renault Kwid approx 5 months ago, Nico Van Wyk was just awesome. My clutch started to make a noise and I requested assistance from Renault Centurion. I was advised to contact a Tanya, who was never at her desk and never answered emails. After constant phoning, Nico eventually went and booked the car in for us. I took my car in on Thursday, 25 July 2019. I got a call about 3 hours later to say that there was nothing wrong with my car and that they would wash it and call me when the car is done. That was at 12h00. Eventually at 15h00, I went to Renault because I had not received a call to say that my car is done. We requested that we drive with some one to indicate the sound that it makes. They then kept the car again to check the clutch again... After I was told there is nothing wrong. My fiance got a call on Friday 16h45 to say that they changed my clutch and they are awaiting approval from the warranty department. Why should I pay for something I didnt approve and my car is ONLY 5 months old. Selina the lady we had been dealing with told us we could come fetch the car, we told her we couldnt fetch the car 9that same day but we could come on Saturday before 12h00. My fiance then got to Renault before 12h00 and was told that the car had been locked in the warehouse and that the field guy had left early for the day. They then told us they would bring the car to me today (Bear in mind I work and have to make arrangements for lifts to work), my fiance got another call today to say they wont be bringing the car back today because Mayfair Gearbox is coming to test the car. My response to this was ***... After struggling and being told there was nothing wrong with my car suddenly there is something major with the car?! Did they even check the car when I originally took it in on Thursday?

I have never had such a bad experience with a car. The brilliant service seems to end with Nico van Wyk. Your service department sucks when it comes to assisting customers.
