Myntra.com — Refund of shakumbhari kurta returned.

Today in morning I purchased a shakumbhari kurta from Myntra, but I placed a return order instead since the quality of product was very bad. And today itself, a delivery guys came to pick up my product. Now I've received a message that my product has failed to pass the quality test and on contacting the customer care, they are telling me that the product was used. Now why on Earth would I use a product when it doesn't even fit me? And all the mrp tags are intact, I'm not going to go around the city wearing a dress that doesn't fit me and also has the mrp tags intact to it. This is sheer nuisance. I demand my refund and that too earliest as many more legal ways are also there .
