Xiaomi India — Ear phones

Address:

New Delhi, Delhi, 110075

I purchase mi ear phones from mi website 5 month before.
After 1 month it's not working good. I submitted to mi service center and they said you will get after 13 days but they returned after one month.
After using 15 days same problem occurs
I was again submitted the earphones on 24th may 2016.
And i am waiting till now (10 july 2016)
When i called to mi toll free number, they said that the product is not available wait for sometime
I can't understand how much time

The worst product which i use ever...
