Myntra.com — order not picked for return

I requested return for order no.[protected]-1454803 purchased from myntra. The request number [protected] was provided. All the tags and polythenes are intact but i discarded the card board box by mistake. Now, myntra is not accepting the product for return although product is unused and unaltered. I am shocked by the behaviour of the such a reputed company that box matters more than the genuine product.
