Engine light on and car losing power

I am frustrated with Ford Dealerships and the car itself. I bought the car last June 2017 and it was on around 15 000 KM, a 4 months later when I was driving I saw an engine light. It was on a Friday, I took it to Ford Hatfield the following day and they managed to remove the light. After 2 days the light was back on, I called ford Hatfield and they said, I must book it in, which I did and they told me they are fully booked I must wait for a week or book with another Ford dealership. I booked with another dealership on the 22/11/2017 (CMH Kempster Ford PTA). They managed to remove the light, but after 2 days the engine light came back on, the available book in date was the 28/11/2017. I took it back and they said, the car must sleep over. The following day I went to the dealership (CMH Kempster Ford PTA) and they took the car, after 2 days it came back on. I booked with a different dealership (McCarthy Ford Silver Lakes Pretoria), the fixed it but after 3 days the engine light was back on. I told them that the light is back on, they told me to book it in, I did and they told me they are fully booked till next year, now it is December 2017 and I need to go home (Limpopo) I took the matter up with the manager and he said, ‘We are fully booked up till next year, Therefore my suggestion is to contact any of the other dealers close to you’. I booked with Ford Hatfield, they were also fully booked and I booked with CMH Kempster Ford PTA they said I must bring the car on the 4th January 2018. I took the car and they told me it is going to sleep over. The following morning they called, saying the car is ready. They sent their driver to come and pick me up, I fetched the car and on my way from the dealership to work the car started losing power, I parked the car on the side and called the lady who was assisting me, she said I must bring the car back, I told them I am not comfortable driving the car she must bring someone to come and fetch it. The reason I told her to send someone from the dealership is because, I heard a lot of incident were car owners were blamed for breaking the car or making it worse because they forced to drive it. I called my insurance to send a tow truck and they did. We took the car back and the manager, they call him JP was not even concern or even apologised, he just said, park the car there and the technician will check it. And he told me to wait in the waiting room while they attend to it. From the experience that I had with the car it sounded like there was something seriously wrong with the car that will need more time and attention. Him asking me to wait in the room was more like they want to do the quick fix as they have been doing all the times I had taken the car in. I am not sure it is the car that can’t be fixed or the technicians just don’t know what they are doing? In all the instances I was never given an explanation to what was wrong with the car and given me assurance that they have fixed it. It seems like every time I take the car back to Ford, it comes back worse. Either way Ford must get to the bottom of this.
