Myntra.com — not returning product

Website:

www.myntra.com

I have purchased a sneaker on 12th of Nov from myntra.com . I try it for only 1 time and i am not comfortable with the shoes and i registered to the return the shoes . On 21th of Nov the delivery boy came and said that it cannot be returned bcoz it is used and said that call to customer care and you can return it then i called to customer care but after our conversation the customer care executive said that i will put a complain and the shoes will be returned. After some time a mail came in which it is written that we cannot return it sorry. I said to customer care that without any try how can i find it is comfortable or not the fabric is good or not . But they are not returning it. So, please help me out.
