Flashstar Commerce — Mobile Micromax IN 1

I ordered Micromax IN 1 from Flash Star Commerce through flip kart. The phone in 10 days after delivery has stopped working. Called up FlipKart, but they say the return polivy ends in 7 days, so they cant do anything. I want to file a complaint against Flashstar commerce who has given me a defective product worth Rs.11, 499/-
