POOR CAR SERVICE AT RENAULT KEMPTON PARK

Last year December i took my car for 90000km service at Renault kempton park. To my knowledge everything on the car was serviced as per manufacturer specifications for major service. Normally if there are thongs that the service plan do not cover, i get notified for example, changing a battery, break pads, fog lights n so on, i would then authorise or decline the quotes. So my car started a very noisy sound on the interior fan after the service, okay i kept on driving the car hoping the sound will stop. So the car gave me engine warning lights, i stoped the car, called the warranty line and they towed the car to Renault Kempton Park. The following morning they told me i need to pay for a V belt R3250,i paid it as i wanted my car back. They never washed the car after fixing it, they ignored the funny fan sound and told me i need to book for fan to be cleaned😭😭😭😭of which i am still gonna pay for it. The service advisor Jerry called me privately telling me, this car is going to give you problems, let me give you sales consultant fro Nissan, the next thing it's gonna break a certain parts in the engine. I don't wanna mention the lady who is the service manager, she has no manners and she is so unprofessional, she called my car, a rats car!! So my question is, how come i am experiencing engine problems if my car is serviced on time?? Renault Kempton Park is a scam!!!!!!!!! I want my money back. I am taking this further. You are going to do 90000km on my car for free like it or not!!!!
