Poor service and bad attitude

My ford focus started showing a light that indicating that the engine is faulty, i took my car to ford and mazda Vereeneging they took the car at service department afterwards we waited for a transport to take us to various places for a long time but white people were dropping their cars and were given transport , we then started complaining about when will we get our transport and they gave us attitude and we were told there are no cars and we should wait. Then after a while we were given trasport at last. Later on i went there to take the car, on arrival i was treated bad because i complained earlier on about their bad service, they told me the engine light was on because it might be a blockage of fuel or leakage and they placed an order of the part that is required to fix the problem which cost around R8000, and i shouldnt drive the car until they get the part so i should leave the car at Ford , i told them i was supposed to be driving to limpopo this weekend as im visiting my wife and kid in Vanderbijlpark,i was busy asking them how long will it take to order and get the part, and how safe it is to drive the car while engine warning light is on, then they told me they are not going to help me anymore since im from limpopo. Imagine now my life could be at risk if i drive this car all the way to limpopo whereas they know very well that most Fords were burning a year ago with faulty engines. They are rude and have bad service .if anything goes wrong while driving this car they should be held accountable.
