Yu Televentures — Yu yunicorn 5530. Network and battery problem

Address:

Coimbatore, Tamil Nadu, 641014

I'm using yu yunicorn 5530 from last 1/12 months. My mobile is draining battery so quickly. Even though if i talk for an hour it draining 30% of charging easily. Battery is worst but it's 4000 mah. For name sake only 4000 mah. Even though network signals are not good at all. Always fluctuating. I'm using 4g sim with volte technology. Same sim using my many friends.in their mobiles network showing fully but in my mobile it's not at all stable always fluctuating or showing only one point. Really i'm not satisfied with the mobile because i have given mobile for service 2 times even though my problems are not fixed yet. While i'm purchasing i'm having many choices of other brands but i has chosen only yu because it's our indian brand so i respected this and i purchase. But i'm not at all satisfied with the mobile. So as soon as possible please resolve my issues. Or else exchange my mobile and give new mobile insted of it or else return my value money.
Thank you
