Car breakdown

My car clutch started malfunctioning hence they had to take the in to determine what the issue is, I found the staff is not properly trained to deal with customer because of the way they dismissed my problem and they way I was made to wait with no assistance on their side. Now they had to removed the gearbox to determine what the issue is but i has happened that the issue are partly warranty related liking water pipe, battery replacement and the clutch kid. I will be according to them have to pay for the clutch but the rest is warranty how is it that when I ask for a report of all these things Deon Van Dev Mescht says that is no necessary I do not think is up to him to make that kind of conclusion am the customer am expected to pay within no proper feedback and contradicting outcomes. I am not happy with this treatment from a car brand i love and who is good with their work but this one is not ayoba at all. I will like to get feedback from Head Office of how they will remedy this messed up situation.
