DTDC — DTDC Courier Missing D45358325

My DTDC courier was not delivered to the Recipient address but over DTDC tracking the Status was showing as Delivered. When we enquire about the courier DTDC person said courier was returned back to the sender. When we asked them why it was not updated in the system they said courier was misplaced and was missing.
