Myntra.com — Wrong product delivered

Ordered a mango top on 23rd February and it got delivered the very next day. As soon as I opened my package it was a different product (top) in the same colour, I contacted their customer care service by writing down the issue to them, they asked for some pictures and tags and after that within 48 hours I got a revert back from them that they can’t take it back because according to them their so called quality check is done before shipping any product. I really need help in this as I am a college student and 1500 bucks is a big amount for me
