India Post — Parcel Not Received and Tracking not updated (AR : CK[protected]IN)

Kindly note that I sent a registered parcel on 19th February from Bangalore (HAL 2nd STAGE) to Kolkata . Today is 3rd March and still the person not received the parcel. Not only that the tracking is also not updated after 23rd February. Its been 12 days now. Nowadays the postal service is become pathetic. We trust india post, but the service delivery is unacceptable.
Attaching the screen shot of tracking.

Kindly do the needful as early as possible.
