Mismanagement of poor customer care service

Last year I bought a new vehicle at Longtom Nissan dealership at Ermelo. I have never enjoyed the new wheels ever since I bought it, the vehicle is in and out at dealership. Last month I took it to the dealership because it didn't want to start they told me is an altornator however they can't assist due to the owner account paperwork. I contacted the owner to my surprise she asked me where did I get her telephone contact without giving me the solution. Till today I'm still stacked with the car that does not operate. I'm very angry with the whole situation to pay a vehicle that doesn't save its purpose, how can a new car have a serious problem like this. This was a bad situation I ever seen. At the same time I would like to know what Nissan South Africa says about the whole scenario.
