Myntra.com — delivery agent unknown

I had ordered 2 products and one got delivered on 14 oct with order number[protected]-2053503. I had done the payment online. I had received the mail and message about the delivery. The number of the delivery agent mentioned in message/email is not proper. He had told he will deliver it to the security guard and now i'm not able to get it. I tried to contact him to ask the guard name but i'm unable to do the same. Kindly help.
