Myntra.com — not able to return product after collecting insider points

Hi, this is regarding order no.[protected]-6213901. I want to return a product (On[protected] since it does not fit properly but i collected the insider point by mistake. Please take back the insider points and also the product. I want to return the product in any way. I have been purchasing very regularly on myntra and they should not disappoint regular customers. They should keep an option to return the insider points and make the return/exchange option available. I would want to return the insider points and the product and get a refund.
