DTDC Courier & Cargo — Consignment number showing invalid

I was supposed to receive a parcel from Delhi. On 30th October I received the message from DTDC saying that the item has been booked with the ID D62457362 however after 2 days I noticed that the parcel has not yet been shipped. On tracking for another 2 days I saw that the status is showing same till today. On travking via sms I got the reply from DTDC that the consignment number doesn't exist. On contacting the company that shipped the item, they said that the item has been given to dtdc. My parcel has vanished into thin air without any trace or tracking ability. Kindly help.
