Worst Experience with Ford

So I was reluctant to do this, but I'm at my wit's end. Yesterday it was the 7th time I had to take my 2014 Ford Fiesta Ecoboost, which I bought in August last year from Ford Barloworld N1 City, to the dealership workshop because of an issue. At first there was a shudder on the wheels, which took 3 tries to figure out that faulty tires where fitted. The I had to return because of my air-conditioning overflow pipe having come off and leaking water into my car. Now I had to return it again because the engine started misfiring on one of the cylinders. I've been in contact with the dealership principal, but he has no interest in looking after his customers. I'm done now, I've opened a case with the ombudsman. The customer and aftersale service is absolutely shocking!! How can you sell someone a car, that went through an apparent 180 point check, and it has so many issues??? I hope I get a response to this post soon, or I will be writing an article in a prominent car magazine, and also some major newspapers. I can not believe how I have been treated by the people at Ford Barloworld N1 City. I'm beyond upset.
