Lenovo — lenovo k6 power mic issue

Address:

I purchased a lenovo k6 power device last month. After use of two weeks the mic creates problem. Mic is not working well. When i contacted to customer care they suggest me to visit service center and replace mic. What the hell is this. I used this phone 60 days only. Why the mic became complaint. I lost my money. I am planning to give a complaint in consumer court.
