Myntra.com — myntra is not accepting returns and given me some points instead

Address: 560037

I ordered shoes from myntra. The product did not fit me well. I proceeded to return the product. On the page, there was some shiny option which said collect points. I mistakenly clicked on it. Then the return option was gone. I called customer care. They told me you have collected insider points so this item can't be returned. I told them the product doesn't fit me and i do not need any points. The customer support person told me this is so unfortunate it happened to you. But we can't accept your return. If this product is of no use to you gift it to someone. We can't provide you any resolution.
The item is of no use to me and it got delivered today only.
