Renault Kiger

I bought a Renault KIger from Renault Heidelberg branch, last year October 2022. To my dismay when I took ownership of the car there were quite a bit of problems that needed to be sorted out. (I also still have the formal letter I wrote to them in possession.) One of the problems, is still a problem and not sorted out. My brakes screeches and sounds like I am driving on metal and this has been an ongoing problem even after Renault Heidelberg had my car for almost a month. I was assured when I took the car that the problem was sorted out just to find out that it was not. I was also told, now please keep in mind that this is my only vehicle, that should I need to leave my car again it would cost me almost R 3000.00 to rent a car from Renault South Africa. The absolute ********** service I have received with regards to a supposedly new (demo) car is just appalling. I would like to know how Renault Heidelberg is going to fix my car. Will Renault South Africa step in? I am due for a service and I have been putting it off because I feel that the service received in the first place was not satisfactory. So where to go? Should I use another branch so that they can actually check and fix what is wrong? My wheels have been taken off and I have been told all sorts of nonsense about rust forming that causes the sounds. If Renault makes a car that can not even withstand normal South African weather or standing outside then why are they marketing a car here? The purchase of this car has surely been my absolute biggest regret and I can just imagine how everyone will try and worm themselves out of this to make sure that the customer (me) pays. I would love to hear what Renault South Africa or Heidelberg branch will propose needs to be done. I have already had the unfortunate displeasure of dealing with one of the consultants stating "That should I be at fault...." . I bought the car like this, I have done my part by sending it back to the workshop at Heidelberg Auto City and I am still at square one. If anyone else has this problem please comment so I can find out what your journey has been like and if your problem has been resolved.
