Myntra.com — sweater by invictus (women)

Address: Bangalore, Karnataka

I purchased a sweater for which insider points were showing, i didn't know what was that so i clicked on it and those points were added to my myntra app details and then it showed that i cannot return or exchange the product, for which i feel disgusted as the product i got is too oversized for me. It doesn't suit my body type and stature. I wanted to place a return request for the same as it cost me way too much for that sweater.
Please help me resolve this issue asap!
