Blue Dart Express — about their rude behavior

Address:

Golaghat, Assam, 785601

I have received a phone call from an unit of blue dart on 14th october 2017 at morning 10:20 am ; he asked my name and arrogantly behaved and told that he is calling from ovali etail unit, not at all any proficiency in communication and instructed me to collect my package immediately from their office because they cannot send the package to the address due to their shortage of staff and they have more packages coming and i am not only one to be taken care of as they have more packages. Or otherwise they will send it back. If any damage they are not liable. The person did not even mentioned about the location of the office.
