Consumer Redressal

I have purchased a jabra talk Bluetooth headset from the fort Croma store on Sunday 5 April 2015 vide bill no. SLF02A026030108179. While purchase the instructions for buying were clearly given to the store representative Mr. Ahmed, that the device is required to be used while travelling on a bike and will be required to be worn inside a helmet. After using the device on Monday it was clear that the device will not be of use to me because the button for answering and rejecting a call is on the outside and is continuously depressed on account of it being in touch with the ear cushion of the helmet. I have approached the store today on Tuesday 7 April 2015 in order to get a replacement with some other suitable headset or some other electronic purchase or a cash back on account of this misselling. Kindly arrange to get me a replacement with an alternative device which meets my requirement or a store credit with which I can purchase another electronic item of use.
