Myntra.com — Return of product denied to be returned by myntra

I order some products from Myntra I kept those that fit me and returned which I did not like or did not fit me. The pickup agent came did not even check the product and said he will come back later. But instead he put up on Myntra wall the products have failed quality check. I have raised so many complaints regarding this and have called them so many times only to listen sorry maam we can not help you. I am even ready to share pictures of the products that they are in perfectly good condition. But they refuse to accept those as well. I want my refund.
