Bluedart — foul play by blue dart

Address:

Kolkata, West Bengal, 700040

As always, blue dart shipment [protected] not delivered when it was out for delivery. The executive called me that he will be delivering in 3-4 hours. But after that he didn't arrive, when i tried contacting him there was no response. If there has been any mishap, noone from bluedart team has contacted me. Why this foul play always happens by blue dart?? Including pilfering and wrong status update and delay in delivering shipment.
And just to mention, i called up nykaa, from where the shipment has arrived, blue dart yet again managed to give a false update that my address is in a no-service area.
