Terrible after sales service for Bessie Bester motors brackenfell

I bought a Isuzu double cab 2008 diesel kb250 bakkie from them in December last year. Ever since I bought that bakkie from them the bakkie has been in 5times and I had I guys coming out to my house to fix the bakkie. The big problem is out of the 6times they worked on the bakkie was fixing the same stuff which indicated in the very first place they took sort cuts in fixing it and the problems comes out again. To name one of the is with my breaks I told them I took the bakkie in to high Q to check the breaks cos it was making a loud screening noise and they said the break disks is done it must be replaced. I went back to the dealer and showed and told they took in the bakkie cos I told I had go to JHB that Friday they saw they gonna fix it for me. What they did they put on some cheap break pads on my bakkie the very next day the loud noise was back. I gave more then enough time to fix these things I also have emails and to prove this. There are still things to be sorted and they don't come back to me on dates when this will be sorted. I need your assistance on this matter.
