Delhivery — Package delivered to wrong person

I had placed an order - Order ID : #ordder956, AWB No. :[protected], to be delivered to a friend in Delhi.

I checked with my friend after recieving the email stating that the package had been delivered. She confirmed in a few days that no such courier had been delivered to her or signed for by anyone at her house.

The signature showing delivery is merely a scribble with no name or phone number or identification. How is anyone supposed to identify if the package was correctly delivered? And can anyone sign for a package and take it?
