I bought mobile by 16/4/2017 after four month the charging is not worked. I gave to near by authorized service center (Mentioned in their warranty card) for service. Four month finished they are not service my phone, but they gave another phone which they sent by company service center in delhi. I returned that phone and i told to give my phone or new one. If the problem is not solved means, the mobile is that much worthless. So i want my mobile with good condition or a new one.
