DTDC Courier & Cargo — Parcel in transit for 4 days

I am sending a parcel from kolkata to Bangalore. The consignment number is F31354408. The parcel is in the same location in Kolkata from last 4 days. If I call the customer care, they are showing its in transit and they have no more updates. They are just raising a ticket for my complaint and saying someone will contact me about the status. So far no one has called. This is really urgent and the parcel has some very importany things. Please resolve this.
