Myntra.com — Refund/Return not allowed

Hi,
I had ordered an outfit from Myntra. As per the return policy, I should be able to return/exchange the product within 30 days of delivery. The size I received was a big size and I want to exchange/refund for a smaller size. When I logged into the app/website, I was unable to create the return/exchange request. I called up the Myntra customer care and they told me that Myntra return policy is of 7 days. But when i had ordered it ws of 30 days. I want a refund of the same.
My order ID is #1167874 [protected]
