Myntra.com — product not exchanged or return

Address: Mumbai City, Maharashtra, 400011

I have purchased almost 5 to 6 product from myntra. And thought to buy more. For 2 products I don't like the material so I thought to return that 2 product. I spoke to customer care, that person told me u can't do return because you used insider points. I am not aware about that point. I said u take my all points but provide me return. they won't allow.
