Myntra.com — adidas supercourt black shoes

Hi, this is regarding order no.[protected]-8160703
I want to exchange my product size because it does not fit me properly. But i collected the insider point by mistake. Please take back the insider points and also the product. I want to exchange 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 i would like to exchange my product as well. Plz its a request to cancel my insider points and i want the same product but in another size. Kindly help.
