Boult Audio — boult curve not working

Address: H.n.26 feroj ghandhi colony

I have purchased boult curve bluetooth headset on 2month from flipcart. After working for 2 months the power button is not working even after full charge.. It is not getting on. I want this replaced.. Please get my set replaced on priority. Also the area where the button is located seems loose. I have tried switching on the headset multiple times but it is not working.. I had expected boult curve to be a great product but it has disappointed my expectations. I want immediate attention to get my issue resolved and product to be replaced. Akram
