DTDC Courier — Shipment not yet delivered

I have booked a consignment with number "F08442353" from Chennai to Delhi on 14th August'14. the delivery of the consignment should be done by this time but when i go and check in the website if the consignment has been delivered or not it says "InTransit" till date it says the same thing but the consignment has not been delivered. when i give a call to your representative they don't even answer the call properly. Reason for not delivering the shipment is no service is provided in the region mention. But why they accepted my courier if no service is there in that region. Then my courier is to delhi University it is in south delhi. Known to everyone in delhi. My document contains application documents for IIFT. Please delivery it at the earliest. Please don't put me in trouble.
