Indiapost — Delivered Aadhar card to wrong person

Address:

Mumbai City, Maharashtra

Our family members Aadhar card was couriered through Indiapost consignment # UE[protected]IN
But the postman handed over the courier to Shankar Yadav of our society without confirming the identity for such a valuable asset.
This guy is in rival with us and doesn't handover the courier back to us...
I request you to please instruct Indiapost to recollect the courier from him and handover to us... How come such a valuable document is handed over to anyone without even checking the identity and address ? Indiapost is ridiculous, they are too lazy to take a lift and deliver the courier to correct addressee!!!! Please take some action on my request and help us get our Aadhar card back....
