Myntra.com — Myntra is not initiating my refund

I ordered a playsuit ( StyleStone, product id[protected] on Myntra and it was delivered to me on 22nd October. I tried it on and I did not like the fit on me So I initiated a return request(within 30 days as per the return policy) and I kept it with the package and the bill exactly as I received it. The return Id is [protected]. Even the tags were intact, I didn't even misplace the tags as I didn't even use the product. Next day the delivery boy picked it up and I received a message saying the product has been picked up but soon I received another message saying the tags are missing. Now why would I mess the tags up if I didn't even use it ? I've bought so many products earlier from myntra and other websites. You guys sent me a defective product and then won't even initiate the return, how is that even fair ? I never had to face this sort oh harrasment before. I need my money refunded !
