Disappointing customer service at Ford

I've received the worst service ever from Ford Fury William Nicol, Sandton. I drove my car in (the Ford Focus) for a noise diagnostic on the 28th of March 2019, late afternoon I received a call from the service consultant saying the car will be ready in an hour's time. An hour later, she called and said the car stopped moving. I asked what happened, she couldn't explain exactly what went wrong. The service manager called and offered to assist by stripping the vehicle to check what was wrong and this would be for my account. In an aggravated state I went to the premises, the service consultant pulled a long face and didn't want to talk to me, she said "I'm getting fed-up" in Afrikaans and walked off. They quoted me to replace the clutch kit for R20000 that they discounted to R12000. I towed the car and took it to another mechanic for diagnostic, what was found was a nightmare. The car didn't look like it's been for service in years and it always went for service with them. The car was still making noise(by pressing it) though they said it was fixed. Last year same thing happened, told the car was fixed, a week later the problem was 2x worse. I found the engine cover was not there, when I called the service manager, he said the model doesn't come with an engine cover. I'm still waiting on him to inform me if they found it. Their customer service is pathetic and the manner in which I was handled was very disappointing, I wouldn't recommend this dealer to anyone, all they do is clean cars and tell you it's fixed.
