Diagnosis that made my car worse than before

Took my ford EcoSport for a diagnosis because when starting the car it would require that I switch the car on first switch off then second time the car would start. When moving it would delay taking gears but once it moves all is fine. We took it to Ford cause we didn't want to drive the car only to find that we are demaging it more. I chose them because I believe they are specialists to ford rather than using back door mechanic. I drove the car there and it was okay the delaying of gears was not that bad. The quote was too high and I declined fixing the car but paid for diagnosis. When we collected the car to our suprise the car could no longer move at all. Their excuse is our car already had fault and it needs new clutch. I didn't dispute their diagnosis our issue is the fact that the car can't move anymore and they refused to take accountability they push blame to us that the car was eventually gonna stop. Which I don't understand because if we could drive it to their shop why we couldn't drive it back home. They have no respect for customers and have no manners to solve problems instead they kept arguing. They eventually agreed to tow the car here and I'm seating with the car that cannot move. Which means if I want to take it to mechanic I must hire a tow truck. Never again will I buy ford in my life.
