Problematic vehicle

I bought a car through a trade-in from Fury Ford on the 20 Feb 2019. I drive it to Durban on the 20 Feb 2019, and my way to Durban the engine light started flashing. I called the sales person and he told me to go to any Ford in Durban. The fixed the issue temporarily. On my way back the engine light started flashing again. I drove it straight to Fury Ford, they fixed the issue temporarily saying it is a spark plug. The issue started again the next day (28 Feb 19). I booked the vehicle in for repairs. It took almost 2 days to find the issue. The issue is the clutch and it will take 4 days to replace. This is not acceptable!!! I bought this car and had it for less than a week and there are issues. My wife cannot even go to work. I opened a case with Ford SA. REF: ********** 82. Please assist urgently.
