India Post — package tracking says package delivered but not received it

Address:

Gurgaon, Haryana, 122102

Since the past couple of months india post has lost atleast 2 of my shipments and with regard to the newest and third one, the tracking shows it has been delivered to the address but i still haven’t received it. Upon calling customer care they told me they can’t really do anything. But how can my package be lost like this for the third time so easily.
