Consumer Redressal

I purchased a phone XOLO Play on 07-10-2013. It started giving me problems like: 1. Overheating 2. Automatic shutdown 3. Voice disturbance during call I went to services center twice and they did some kind of software update and returned back. But again faced the same issue. Then third time when I visited they registered my complaint and asked me wait for 25 days. They gave me handset after 30 days but I am still facing the same issues. Now Service center has again suggested me to submit handset for 25 days, but now I am thinking about filing a case in consumer court. Kindly suggest me for the same.
