Myntra.com — Not processing refund for unused packed product

Address: Bavdhan, Pune

I had returned a jacket which was ordered by mistake, without even opening the outer cover. All brand tags were intact. After pickup by the Myntra guy, I got a message from Myntra some time later saying that it failed quality check and refund would not be processed. I am surprised, as the product was not even opened by me. I tried calling the pickup guy, but couldn't connect with him later.
Request you to look into it on priority, and provide an update.
