DTDC Courier & Cargo — consignment no. 50319440

It was sent by me on 22/2/18 in Bangalore to Bapuji Surgicals, Kudlu Gate, Bangalore 560068. Online tracker of DTDC shows it as delivered on 23/2/18 at 7.30 pm when the company office was closed.
There is no name, phone or stamp of the receiver. It is obviously given to some other person. Our request to trace it back and deliver to the rightful address ahs not got any response.
The online tracker doe snot have any option to lodge a complaint.
I downloaded their android app and logged in as a Guest but here too it says " You cannot lodge as complaint as consignment has been booked or delivered".
Please help me recover this valuable consignment and ask DTDC to deliver to the correct addressee.
