poor car quality by Volkswagen South Africa

I bought a Brand New VW Polo Vivo Trendline at MC DULING MOTORS, The car started giving a problem of tail gate lock less than a year. I booked it for repair. Later the car started developing a radio problem, I booked in for repair, now the car is giving a radio problem again. VW-SA is no more producing quality car, People should be aware of this substandard production of polo vivo
