Myntra.com — Received defective product still the delivery guy rejected the pickup without checking reason why I am returning the product

I have ordered a Levi's jeans in Myntra EORS sale as it was on great discount. Product I have recieved was defective so I've raised exchange for the same. After 4 5 days person came to pickup the product and denied the pickup saying it is used and smelly. I told him I've raised exchange because it is used and smelly and he kept my exchange on hold. I had such past experiences with Myntra. Very disappointed with the delivery people and Myntra policies. If you can't take returns of products even if it is used and smelly please mention the same on the app. Don't make your customers fool.
Your inflexible policy will in turn loose your customers faith in you.
