[Resolved]  India Post — status is showing 'item delivery confirmed' but not delivered to the receiver.

Consignment no. Eu[protected]in
Status is showing 'item delivery confirmed' but it is not delivered to the receiver. It has been 3days it showing. I have sent a parcel through post office from lucknow, up to nalanda, bihar. On 16/12/19 status is updated like 'item delivery confirmed' but when i asked to receiver, i got that it is not delivered. I put contact number of receiver also on the package of parcel but no calls he received from any postman.
