Myntra.com — I am not able to return a product after insider points collected

Address: New Delhi, Delhi, 110045

Website: Myntra

I've collected the myntra insider points by mistake and now i'm not able to return the product even though size is too big and don’t even need points, i want to return the product in any way. I called the customer care and they also told me they cannot revert back the insider point and not able to help me in return process. Top is not fit to me and it is total waste for me. I would want to return the insider points and the product and get a refund.
