Myntra.com — I'm complaining about exchange policy

I had ordered a roadster man green cotton jogger on 2 Feb but on the very same day due to some size issue was there I made a request for exchange. But at the time of exchange delivery man denied to exchange after giving me the reason that the product was used or having some color faded issues. After that I was made multiple requests to the customer care and ask them to solve the issue but every one giving me the false promises. I even don't remove the price tags from the product. This was the 2nd time when i found such kind of issue. Last time I got a product without the price tag and when put a request for exchange or return your delivery man denied to take time product back. In such cases why customer will bear or pay the price for your fault. This is totally annoying or misappropriate behaviour from Myntra. Totally disappointed once again.
