DTDC Courier & Cargo — parcel not received even after 10 days

My consignment no is d37591315. I was supposed to receive the parcel in sambalpur, odisha and it was parcelled from delhi. Even after 9 days, i have not received my courier and i do not know about its whereabouts. 2 days back, the status showed that it was returned (When i have not received any parcel) and now it shows in transit.
The courier contains very important document. That is why i request you to take strict action and help me retrieve my courier soon. I am attaching the tracking shipment details.
