[Resolved]  Myntra.com — Quality check failed and return decline for false reason

I ordered a Nike dri- fit Challenger track pants delivered on 2nd August. I tried it but it was little too fit for me so i decided to return it. It was picked up today by the delivery guy . I remember exactly everything was intact with the product . After a few hours, i got a text on my phone saying your return didn't passed the quality check and is declined becuase of the price tag was not intact . The price tag was intact and the delivery guy confirmed it on my doorstep. So Is this my fault that i ordered the product from Myntra and didn't chose Alternate brands like Flipkart and Amazon?
Please assist this issue and initiate my refund.
