Xiaomi India — My phone is not working : redmi note 3

Address:	560103
Website:	www.mi.com

My phone is not working. I have raised concern immediately. I called in customer care they asked me to visit their service center in kalkaji. I have visited over there and they found that it has some hardware issue.
Immediately i sent email to xiaomi with job card which was given by their customer care and raised request for replcaement.
They have accepted the request as i have updated them on time as per their policy. One day i got call that some person from blue dart will come to collect my phone and once they checked it they will send new handset to me.
From last 15 days i am calling them again and again but i am not getting any proper update each time they are giving diffeernt updates. From last 10 days i am sending mail to them but they are not replying to me.
Please help me.
