Indiapost — my shipment rx[protected]de did not arrive even after 45 days

Address:

Delhi International Mail Center

Shipment rx[protected]de did not arrive even after 45 days of shipping. The status on the indiapost website shows that it is stuck with delhi international mail centre since a 40 days.

This shipment has critical medical supplies for my mother. I have not been given any information on what to do about this delay or what is the reason for this delay? What is going on?

At the bare minimum i need an assurance that the shipment will arrive late, but even that is missing.
