Myntra.com — Myntra Return Failed in Quality Check

I returned my order as i received from Myntra with all the tags intact without using the product, later they sent mail to me that my refund won't be processed as it failed in quality check.
The person who collected the return didn't said anything about the product that it isn't correct or bad in quality.
What quality check parameters the product failed in i have no idea, they haven't even mentioned anything. And they stated that issue is resolved.

I want my refund for the Product.
