Consumer Redressal

I have lodged a compain on 15th August to Hitachi Customer Care since my AC was not working. Since then its already been almost 3 weeks. But still the issue AC has not been resolved. Their technician visited twice but he could not resolve the problem. Seems that technician is not efficient enough. During this period I have called several times to hitachi customer care but they did not do anything. My complain request number is 13081500598. I\'m suffering a lot due to this kind of poor service from Hitachi.
