India Post — untimely delivery of speed post.

This is regarding a delay in the delivery of my speed post which i had posted in pune gpo 411001 on 11th august 2017 for a delivery to noida 201301. The last update was on 14th august 2017 when the item reached maharishi nagar so 201304 and after that there has been no movement and no updates either. The number is em[protected]in. Today it is 17th august 2017 and the post has not yet been delivered despite it being a "speed post." i would request you to look into the matter and resolve this issue.
