DTDC Courier & Cargo — Shipment Undelivered because "Receiver Not Available"

I had couriered a parcel containing Rakhi and Chocolates from DTDC Express Limited, New Garia (Kolkata-700094, West Bengal) on Wednesday (18th August, 2021) via 'DTDC Plus' (Consignment No. : V[protected]. The parcel is supposed to reach my brother at Jalpaiguri Government Engineering College, Jalpaiguri, West Bengal, for the occasion of Raksha Bandhan. Since Raksha Bandhan is on Sunday (22nd August, 2021), to ensure that the parcel reaches him on or before Rakhi, I availed of the 'Plus' service, paying Rs.395 (i.e. Rs.75 extra as compared to the normal delivery service). It was moving as per schedule and given the steady progress, I was more than sure that it would reach him by Friday evening or, latest by Saturday morning. Now, at this late hour of the night, the tracking history shows "Out for Delivery" at 16:41 Hrs and "Not Delivered (RECEIVER NOT AVAILABLE- (CIR))", at 16.47 Hrs (both updates dated 20th August, 2021); whereas the truth of the matter is, my brother had been in his hostel room all throughout the day (on August 20, 2021) and certainly accessible on his mobile number (in fact, I myself had a telephonic conversation with him at around 15:30 Hrs). Moreover, the envelope bears two mobile numbers of my brother as well as my contact number. I wonder if the delivery person had at all gone anywhere near the hostel (which is the place of delivery) because had he, then other boys putting up there would have surely done the needful so that the parcel does not return unattended. The delivery executive could have also called up on my number, which he did not consider either. With less than 24 hours left for the auspicious occasion of Raksha Bandhan, here I am still composing complaint messages and mails, hoping against all odds that the shipment would reach my brother before Sunday (22/08/2021) and my brother is planning a visit to the local office at Jalpaiguri (the one near his college) today, i.e. Saturday morning, just to recover his Rakhi gift sent by 'Didi'! And all this even after availing of the high-priced 'DTDC Plus' which guarantees "EXPRESS DELIVERY". What an irony! Is this the price I am supposed to pay for entrusting the "MOST PREFERRED COURIER COMPANY IN INDIA" with the responsibility of bridging the gap of 700 km between me and my younger brother on this Raksha Bandhan?
