Bad Service

I purchased a new Renault Clio IV Dynamique July/August 2014. I experienced squeaking of my brakes at the beginning of December 2014. I contacted Renault The Glen and was advised that I may bring my car in to process a claim, I booked the car for 28/01/2015 at 7am. I received a call after 9am enquiring authorisation to repair the brake pads after which I would pay R1,670 and that the brakes of this type of car gets changed at 12000km, to my knowledge this is then poor quality.. The lady advised I may claim afterwards but there is a possibility I would not get paid. I refused and they advised the assessor from Renault SA would be later the day there to assess the vehicle, I received a call before 4pm asking if my car can stay there as the assessor did not arrive, I was not offered any courtesy car and neither an apology for the inconvenience. I was advised that the assessor would be there the morning 28/01/2015 no time can be given, I called the morning to which I was advised that they don't know where he is??? I feel this is really bad after-sales service and really bad customer service, this is definitely the last Renault I will purchase, after this type of service.
