DTDC — Parcel not delivered at the correct address

Address:

New Delhi, Delhi

I had couriered one parcel from Delhi to Kolkata on 18.12.14. My DTDC Consignment number was D19269352. The courier has not been delivered to the mentioned address whereas the status in Tracker is showing "delivered". Even after contacting the DTDC staff at Delhi & Kolkata, i'm not able to track my consignment. DTDC staff at Anandapur(Kolkata) is saying that they had already delivered the parcel, the delivery boy is not sure at which address he had delivered the parcel. They are saying that maybe they had delivered the parcel at some neighbouring house. It has been two months now and still the parcel is untraceable & there is no effort from DTDC. I had wasted so much money for my loss of parcel.
