DTDC Courier & Cargo — Haven't received my order

My package with AWB Tracking No.: X64504795, status is "Shipment Returned due to RECEIVER NOT AVAILABLE" and last status is "Returned parcel delivered ". There were not a single attempt to deliver this packet to the address. It is my residence address where someone is always available. I also called DTDC Delhi office and gave them the tracking number but they were very rude and said they don't know about it before they hang up the phone. When you accept a packet, you commit a delivery. All courier company attempt delivery at least 3 times before they can send a packet to the sender. I would like to know on what ground this packet has been returned? I want my order back asap.
