THE WORST SERVICE IN SOUTH AFRICA

I have been waiting over 2 weeks for a factious Report from the time I told them to please take a look at my Brake AS MY RENAULT DUSTER IS ONLY 6 MONTHS OLD BRAND NEW OUT THE BOX, But I have been complaining since the second month I have had the car. Now, how I no that they didn't even bother to look at my car, but they were quick to ask if they can keep my car overnight when I was on my way to collect my car. anyway I took photos of my speedometer when I dropped my car off, and when they dropped it off I took another picture, Its exactly the distance from Midrand Renault to my Work in Sandton. It is DISGUSTING that Im paying for a car I cant get a good service on. They tell me there's nothing wrong with my brake nor the squeak in my steering when I turn to the left, but every day the noises are getting louder and louder. Now im fearing my life and my children life is in danger as these brakes are NOT RIGHT..... COME AND DRIVE IT YOURSELF AND WHEN YOU DO HEAR AND FEEL THIS YOU WILL BE ASHAMED TO HAVE DONE THIS TO YOUR CUSTOMER. I have been running after PETER, JAY everyone at the Customer service at RENAULT SA, NO ONE ever gets back to me. WHAT ARE YOU GOING TO DO ABOUT THIS
