Suzuki Strijdom Park - Angry customer

I Bought a vehicle from Suzuki Strijdom Park. Ahmed assured my nothing wrong with car. Asked him about the whipers not working properly on Dekra report. He said it will be fixed in their workshop. When I got to the dealership, Gideon showed me the car and said I can take a test drive later. Then he just took me to finance, without the test drive. If I'd driven the car before purchase, I would never have bought the car! They never replaced the whipers, car has no power. When I complained to Ahmed, he said I can't return the car an he will speak to Gideon about not taking me for a test drive first. Wow! That hrlps me how???? I feel they saw a single women coming and took advantagr of that! I will never do business with them ever again. Stay far away from this dealer people!
