Boat — 1 warranty product out of 2 not given

I have filed a complaint in June claiming my headhones not working. I have bought 2 headphones and both were not working, so given them for replacement. I have been given 1 headphone and other not given, inspite of writing infinite mails and complaints no repsonse. No proper support, and i feel the customer is cheated in this indian market by these companies. Kindly take strict legal action against them.
