POOR SERVICE AT CAR SERVICE CITY

I took my car for a major service at the Montague Gardens Branch as usual on the 28 September (Wednesday). 1. They took 5.5 hours to do the Major service. 2. The next day the 29 September I was stuck in Cape Town Civic Centre, the car not engaging on gears. Towed the to car services city Montague gardens. (For a car that was not giving me any issues when I took it to car service city). Spoke to them and they first suggested that the clutch had a problem and replied and said there was no chance it could be because the clutch kit was changed a year ago and flywheel skimmed and the kit was LUK. They then suggested that the bearing might have collapsed. The next QUESTION is why was this not picked up if the car came to the branch with a faulty clutch. Took the car to a private mechanic only to find the pressure plate was broken and not opening for the input shaft. (Note: when a pressure plate is tearing/breaking (normally) the is a certain squeaky/springy noise that comes from the engine bay). Took the pressure plate to the Branch. They still insisted they were not aware of it. Yesterday I took the car for alignment, only to be told the wheel bearing and shock are bent. Why was this not picked up on the safety check? I AM VERY VERY UNHAPPY WITH THE SERVICE I HAVE RECEIVED FROM CAR SERVICE CITY MONTAGUE GARDENS. I WILL NEVER EVER SET FOOT IN 1 OF YOUR FACILITIES. THANK YOU
