We have a hunter machines which has issues quite often. Your mechanic, Mike, has been coming for the past month, month and half, and still can't find the problem. He keeps on checking in through a "trial and error" system, he keeps replacing parts that do not need replacing and he keeps charging us but the problem remains. Because the mechanical was unable to complete his job within a month and half, our customer were very unhappy and kept complaining to us that the alignments of their truck were not good. This keeps happening because Mike keeps on saying that the problem is fixed and that the alignments should get better but they don't. In fact, they get worse. We are suffering because a designated Hunter repair man can not fix our Hunter machine. So many of our customers were unhappy with their alignments that they gave us really bad reviewed and therefore ruined our reputation and our credibility. We should not be loosing customers because your staff is incompetent and doesn't know how to get the job done!!!
