Faulty dvd player

faulty dvd player sold by croma, malad west.
withing 2 weeks of the purchase the dvd player stopped working.
DVP5996K is the product number. The service center people came home and took the player, for 1 month they said the required part has not come, and then after that since 2 weeks they are saying that we are replacing yr dvd player. Philips is giving false promises. Please help me how to go about solving this.
