Boat — boat airdopes 381 bluetooth headset right side

Address:

Sigma Enterprises, #565, 6th Main Road, 4th Block, Rajajinagar, Bangalore-560010

I have purchased boat air dopes 381 bluetooth headset from flip kart.
From past 15 days, the right side of the headset is not working. I had been to service center but they told that this service is not available here. As it is under warranty basis, i request you to replace the headset as soon as possible.
