Renault Polokwane are *****s

I took my 5 months Renault Kiger to Renault polokwane with widows that are not working and a car that is loosing power. To check and diagnose the car they want money. R1600 and the found out that it had wiring problems. To strip the car they want R3600. The money exclude fixing the problems and for a car that is under warranty. Renault Polokwane is de*****ing people. Warranty with Polokwane is just a myth.
