Lyf — about phone

Gurgaon, Haryana, 122003

I have an lyf flame 7, i bought it for last 9 months, it started problem in working, i contact the service center for the problem of my hand set but the service they provide cannot satisfied me, it started problems within 2-3 days of reparing by the service center and now i again went to the center for the same problem and now they tell that its battery cant work properly so you should buy a new battery.
I request the company to repair my battery but they told me that it is now not in warranty. When it is in warranty they don't do nothing after the warranty finish they find the problem. So i again request the company to repair or give me another handset as possible.
