Unrealisable car brand and worse customer service

Nissan magnite is an unreliable brand and Nissan customer service is even worse. I bought a brand new Nissan magnite in December 2022 8 months later the engine light is on and this 2 months after it’s first service, i took it back to Nissan service centre on the 5th of september 2023 and I was promised the car would be ready the following day. Till today they can’t fix the problem, and I have been promised a courtesy car but that is not happening too , every time I call go update I’m promised tomorrow like a kid. I tried to call SA Nissan customer service but they failed to assist me. They never called to find out if my issue was resolved I am now going to the 3rd week. And this is disrupting my work and finances as I have to pay extra to get to work I don’t want anything to do with nissan brand , it’s very frustrating to be .without a car for two weeks and no any alternative from the dealership this car brand that is unreliable I don’t know what will be the next problem on the car if they give it back I am going to write to the ombudsman, they must just reverse the who deal and relate their car back, I will find another car brand.
