India Post — misplaced speed post

Address:

Khordha, Odisha

Sir i send rakhi to my brother who study in kiit on 9 august.
Rakhi is received in post office on 13 august but till now it is not delivered to the my brother
And they didn't give any reply when we call them just give no of one other person
So many times i call them request yhem to delivered rakhi but they didn't listen
What kind of service is this if they didn't send parcel on time then why this post office is open it to we send online delivery that is more better
