South Africans DO NOT use these Foreign dealerships in Johannesburg

I bought a polo vivo tiptronic from them last week, on the 3rd day of driving it was already over heating n took it back showing water sign and the very same day they claimed to have repaired it therefore should collect it. only drove it for one day then this time it was leaking water, radiator issue,water sign back on and made sounds when i reversed all the time. As I type now, had to pay R1000 to tow it back to them and requested a refund only to be told by Meyer the ***** salesman that his boss hasn't arrived. I need a refund of that R1000 for towing services. This car needs a whole new cooling system..thats it.That time they claimed to have given me a discount of R10000 which is not not true and demanded I pay R4500 for admin costs which I only paid R2000. At first the car was R100000 then in the afternoon it changed to R105000 including admin fee of R4500 and when i was about to take the car home the price changed to R105000 EXCLUDING admin fee of R4500 that's when I told the ***** salesman that I will only pay R107000 for everything. As I am typing this email now, the car is currently with them claiming to be repairing it.If they do not repair it correctly, I need my full refund. This car is not even a full week with me and already having problems with it.
