Consumer Redressal

I purchased Micromax(A106)on 24 April,2015. After two month I faced a problem with display & went for servicing & I left my phone in service center for 10 days.After that I again faced a problem with Not recognition of external SD card & again I went for servicing & left my phone for another 15 days.Then I got a call from service center that I can receive my phone..Then I went center to take my phone back then I found that my mobile back cover has been changed & problem for which I gave my phone for servicing that was not solved then I kept my phone for another 3 days.After that I faced software problem after that now I facing problem with battery.
