Myntra.com — missing product: which shows delivered and actually it doesn't.

I had ordered 3 items (2 pair of jeans and 1 shoes) amounting to 5596.35 rupees. Of these, i received the delivery of 2 items only. The shoe worth rs.2300 was not delivered. Neither the delivery agent nor the customer service executive has given a satisfactory response as to why this hasn't been delivered. Moreover, in a really irresponsible manner, he has brushed off my complaint saying that they were not responsible for the missing item. Who else is responsible, i would like to ask. This kind of passing the buck attitude is not what we have come to associate myntra with and this, therefore is totally unacceptable. I am not asking for a refund here. I would like to know why the product was not delivered and would like for it to be delivered to me as soon as possible. I believe that this is in fact your responsibility and if your executives don't think so, you are not fit to be in this business.
