Myntra.com — Not returning

Address: Sec 79, Gurgaon

Website: Myntra.com

I got two similar products (Kurta sets of Manyavar) of different size as don't have enough time to wait for exchange size if one goes wrong.
But Myntra has set that to only size exhangable and not returnable where all of the products in this category are returnable. So I haven't looked for its policy of which I got trapped of their gimmick of selling.
I have lost Rs 6000 due to it and they are not agreeing to return even a single one.
