Xiaomi India — Malfunctioning

Address:

Kanpur, Uttar Pradesh

After the updates my xiaomi redmi 1s started heating very much. I was shocked as the update mentioned it will resolve the heating problems and battery draining problem. I complained about it in one of near by xiaomi centers but u don't know what they did with my phone. They just made it worse. Heating problem is resolved upto 10% only but battery drains equally as before even now my handset had started malfunctioning. I don't why sometimes keypad doesn't opens at all because of which I am not able to send a single Hi also to anyone.. Music system is no more working correctly. When music is playing at back and I open a new app it suddenly stops and playing it again starts from the beginning.. I am annoyed by this as I cannot close the music screen and listen the songs. It's just 10 months around and this phone I guess seems exhausted. I am not getting help from any centre. Please tell me what can be done...
