Address:	122003
Website:	www.mi.com/in

I bought this phone from http://www.mi.com/in/. After they delivered this phone i faced issues with network fluctuation & battery issue. I complaint them, than when ever i mail him they just replied the same, like a template based reply, I have also attached screenshot for this. It already 10 days, but there is not solution i got. they are also not giving any expended warranty for that, they saying will give you warranty from starting date
