Treated as 2nd class customer

I called the service Manager Danie at Allen Joss to inform him about my dissatisfaction in the service I have gotten from his team and himself (when I informed him and did not act) in September when I had taken my car on for service. I further informed him that since they had worked on the car on the 12th of September there has been a sound when I brake. The service manager was very rude towards me, and told me he will not check my car. He basically told me I can go jump off a cliff and get was shouting at me.
