unhappy customer with nissan in nelspruit

I recently bought a Chevrolet utility bakkie at nissan nelspruit and had the worst service possible.I bought this vehicle on the 24th of August 2018 from them and after not even driving it for more than 300 kilometers and less than two months it broke down.I got it towed to them and after three days they tell me it's the cambelt that supposedly came out.it took them another three days to replace the cambelt.for the entire week I had no vehicle and was left stranded.I was told by the sales manager Kevin at nissan in nelspruit that they don't give courtesy vehicles and only have bank owned vehicles on their floor.after I had to go and fetch the vehicle from them which is 50 km from where I stay I had the vehicle for one week and didn't even drive it 100 kilometers and it broke down again.I got my insurance to tow it to them and only after a week they tell me that one of the valves on the engine was bent.the second time it broke down was on the 10 th of October.After I posted what terrible service they offered and that they sell defective vehicle to customers did they decide to give me a courtesy vehicle which apparently they had to pay the bank 150 thousand rands to give me as a courtesy vehicle.the vehicle they gave me was a np200 which is falling apart the ball joints on the vehicle is shot and it smells like something died in the vehicle.after the second week I phoned Kevin and he tells me they still fixing the vehicle.Three weeks has gone by and I the vehicle is still not fixed.Kevin keeps promising me the vehicle will be fixed by the end of the week.I am totally disgusted with the service and product from nissan in nelspruit and nissan international must intervene
