Business should close

Took a car for master clutch cylinder replacement and major service, what transpired is the master clutch cylinder was not fitted properly I went back and they had to flush the clutch, then the problem again occured, it was as if I didn't put in the clutch cylinder, I had to go to another clutch place they checked and saw they didn't fit the master clutch cylinder. The second place didn't Even charge me. OK secondly I told them to do a major service, I can tel you now that the car oil was seen low only to find the oil is leaking, my question if that was a major service why was it not detected and me being told off with the feedback letter after the service. I'm very unhappy with fix it and these many people who are complaining about them.
