Renault Motus Boksburg.

I am having a headache experience with Renault Motus select east rand Boksburg - I bought a brand new car - the window rubber is damaged on the driver side. They keep on making promises that it will be resolved, I have been through every person at the dealership and nobody seems to take it serious. It is now 6 months and I am still waiting - every time i go to Renault they promise that it will be done and it is ordered - they say they are waiting for the ship to come with parts. I think the part was on the Titanic cause it never made it. It is terrible to think you buy a brand spanking new car and then you have to wait for every for a rubber to be replaced - very bad service.
