Bad aftersale service.

I bought a vehicle from one of their agents in KZN and got a 2 year/50 000km warrantee on rust. The vehicle was not even 1 year old, under 25 000 km and it started rusting away. Quotes on repairs vary between R 50 000.00 & R 85 000.00. First they made me a "goodwill" offer of R1500.00 towards the repairs. What an insult! What happened to the warrantee? Now they don't want it to be repaired in my hometown (Richardsbay). They want the vehicle to go up to JHB so that they can have a cheap repair job done on it..... I am going to take the matter further, you can not give a warrante and not honour that warrantee. I want a new vehicle!
