Myntra.com — no refund for shipping charges

I have returned a product worth rs 463 which is the total amount whereas, myntra only refunded rs 314 claiming that they dont refund the shipping charge amount. This is the first time i am facing the issue. People rely on mynta all the time and am a frequent customer of myntra for past 3 years and this is what they return to us. I believe this policy has to be withdrawn asap orelse the customer will be in loss.
Kindly work on this. Our money are not just to be wasted in vague. And if this continues people will no longer rely on ecom portals.
