Don't ever buy a Renault

Don't ever buy a Renault. A day before my Renault went in for service I had a problem where the fan would run long after the ignition is off, I informed Renault of this issue on the service day, after the service was done I drove the car for 1 day and it started overheating. Now I'm sitting without a car and stand to be billed R8900 for an engine diagnosis. This is a pile of ****. I took my car in on Friday and I only get contacted at 3 on Monday with an update. How do I get around in the meantime, of course they have a **** policy that the part must be ordered from France before I can get a courtesy car. How do I take my child to school, how do I get to work? AND WHEN YOU CALL THEY KREP YOU ON HOLD and just disconnect the call. Biggest mistake of my life. Don't buy a Renault
