Gonoise.com — smartwatch is defective

Address:	Gurgaon, Haryana, 122001
Website:	www.gonoise.com

I have bought a smart watch from www.gonoise.com with order id 300040 at a price of ₹1799 in cash and kept it as a gift for 2 weeks. But after a single day use its display stopped working along with a button.
I made a return request via mail and they replied to show the product details with images. After seeing all details they ready to accept the product and suggested to courier the product at nexxbase marketing pvt ltd, plot no. 22, sec-33, near infocity 2, near hero honda chowk, gurgaon, haryana-122001. Then, i need to spend ₹100 more for the courier. They received the product there and send me a mail for the cancellation of product. Then i send the concerned account details for the refund but they denied and asking for replacement. Now i am not interested in buying this product from such a worthless organization who do not have the customer rights.
Rest details are providing by the images.
Please help me in the refund of the money.
