Bad service ever

I arrived there at the dealership around 7:15am . Nicollet was my service advisor ,she opened a job card for me and said to me she will see what she can do for me . I went to Eaan service manager told him what is my car's problem he helped me by taking it to the workshop and I explained to him that these problem I am having has been there for a long time since I bought the car from them .everytime when I take my car to the servicw I tell them to check handbrake and abs sign come on and after some time they fade away . I was told nothing they can do if they dont see it And I should drive by when these happens if I am around so that they can find out what is wrong with the car. The other day I drove in when the signs came on and they told me that the technician was on leave. So these happened for a year, only now the technician was in . My car gaved me the problem and I went in and Shaun was helping me and the service was bad and then they phone me to know how was the service out of 10 I said to them bad 3 he insisted I give him 10 ,that is when I stopped taking my car for service to be helped him ,I even told Eaan about my problems he helped me again the good manager. these people Nicollet and Tanya are helping me thus far but I am no longer getting phone calls from the customer service for feed back after Shaun Insisted I give him 10 . I own two hyundai accents and I have been servicing them there but the other car I am not doing it there anymore,because I was told I complain too much and I am planning to take my other hyundai to the different place after what I saw happening to me . Nicollet told me that they have to charge me for labour they did on my car of fixing the problem as I was not advised initially and I diclined and told her I wont pay as I have been reporting these problem for a year now since I bought the car there in centurion. She was angry and banged my car keys and said 'take your keys and go I'll see what I will do' Bad service from centurion hyundai. Me and my brother we no longer getting the good service from there .I am so sad and angry.
