Bad service, rude manager

I took my car for a general service on Friday 11 December 2015. Upon fetching it, I was told that there were a few parts that I had to pay for. I asked the service manager, Hayley van Zyl what the problem was and she told me that they had broken the filter assey when the car was being worked on because the car is old and old cars' parts break off when worked on and I would have to replace them. My car is a 2013 Toyota Hilux. I told her that it was unacceptable to which she responded with shouting at me, \What do you want me to do about it!"Ms. van Zyl then threw the service invoice papers at me. I left the dealership quite unhappy and when I drove out my \""open door\"" sign was on"
