Myntra.com — Order is not delivered on the deadline.

Sir/Madam,
I ordered product from myntra app on 13th November 2016. My order id is[protected] and shipment id is[protected]. Myntra upgraded my order and promised to deliver on 14th November 2016. But they fail to deliver on 14th November. I do not receive any response from them in response to the failure of delivery on deadline. Next day, i.e, on 15th November 2015 I receive message at 09:53am that their deliver man is out for delivery but I did not get my product. I also called their customer care service, myntra's executive replied me that I will surely get my product at 8'o clock. But I did not receive my product. Now they e-mailed me that there are many unsuccessful attempt to delivery your item if there is one more unsuccessful attempt then we will return product to fullfillment centre.
This is not my fault at all. If they are unable to deliver my goods then why should I suffer?
Earlier also they invalidated coupon worth Rs.400 without any reason.
So I request you to take necessary action and help me in this regard.
Yours Faithfully.
