Myntra.com — not accepting returns/exchange

I bought a boat blue-tooth earphones on sail and when i received the product i found out that the sound quality is really bad, also the blue-tooth was not working properly. When i tried to return/exchange it on the next day the executive said that these products are non-returnable and they can't help me in any way. Also she made the statement the the product of myntra are 100% genuine and original. Indirectly she was saying that i am lying to them about the quality just to get it return or exchange. They gave me bad product also made me a liar and did not listen to me at all. I wasted my thousand rupees on an earphone which is not even worth of 100 rs. Highly disappointed. Please do not buy electronics from myntra. Instead buy it from amazon or flipkart.
