Overnite Express — package not yet delivered

A package was urgently required to be delivered from jagiroad assam to badarpur assam, it was confirmed that the package would be delivered within three days, however even after 7 days the package remains undelivered.
The tracking system is not at all being updated and it seems that there is no system alert which can alert the company of ensuring timely delivered failure.
