Blue Dart Express — not even attempting to deliver, but prompt changes in the status

Address:

Banjara Layout Main Road, Horamavu, Bangalore, Karnataka, 560043

My particular consignment has not been delivered but i am surprised to see status changes.
There is no call or even an attempt by the delivery person to get in touch and directly changing status to consigne not available is an easiest excuse.
Very bad experience and is happening the 2nd time.
Very keen to see what they change promptly on their status tracker.
