Xiaomi India — Return issue

Address:

Agra, Uttar Pradesh

I have purchased a redmi 2 handset from mi.com Xiaomi's official website. From the first day it was delivered there was severe problems i have faced in it, there was something wrong with the battery and camera so i filed a return request for it.It was delivered on 1 aug 15 and i filed the request on 2 aug 15 as in 7 days after recieving the product as per company's policy but till now no return/refund is made neither any official took the handset for diagnose. So please i request you to look into the matter .
