Myntra.com — not received my order of a kurti on myntra app and didn't return money either

My name is kalyani. Before some days i purchased a kurti on online shopping app myntra. I paid amount of 554 rupees for the same order by using my atm. I was waiting for my order to arrive. One day the delivery boy came to my house but i couldn't receive his call. After some time i called back on that number so the same delivery boy told me that he will come tomorrow again with the order to deliver. But he did not come the next day and i received a text saying 'order is delivered'.
I called delivery boy but he did not answer my phone. So i waited for some days but he did not come. Then i called consumer complaint number of myntra, the lady said order has been delivered. Or you should have complained the same day when you received text message of parcel being delivered. Its last now and she cant do anything about it. These are their rules.

I did not receive my parcel. And also my money is wasted. That was a mistake by delivery boy. He didn't deliver my parcel.
Either make delivery or return my money back.
