Myntra.com — empty box received and I want my money back

Address:

Jodhpur, Rajasthan, 342011

I ordered mast&harbour shoes, i received the delivery on 31.12.2018 but when i open the box it was empty, i received nothing inside the box except some packaging papers. After that i called the carrier, and they told me it they didn’t do anything and it was already like that when they delivered it. And the package is perfectly sealed and no tampering. It is very disgusting i usually do shopping from myntra but now trust is broken. I think that this must be a problem in the warehouse and the packaging department forgot to put the item inside.
I want my money back.
This is my order details
