Myntra.com — wrong product received from myntra and denial to return

Website:

Myntra.com

This month i had ordered a jeans from myntra of the brand 'all about you - women jacquard side tap mildly distressed jeans' but they sent me a wrong product. The product i got was different as shown in the image of order. When i created a return request of the same the pickup person denied to take because the product didn't match. Then i tried contacting myntra and they told me they raised a complain against this and that they will retry the return. After the complaint was registered by them again a person came to pickup but again he denied saying item not matching with pic in order. Now tell me if i received a different product how the image will match? Myntra told they'll take it but they denied to take. Today i again complained the same but i feel that same is going to get repeated. I want strict action against myntra.
