Blue Dart Express — refuse to deliver courier to my address

Address:

Sivasagar, Assam, 785701

I ordered from amazon, but the courier boy refused to deliver my product at registered address, asking me to collect from their office, it's better to shut down your service as you people harassing customer in the name of door to door service, there is no service at all, i supposed to received my product by yesterday, only because of your poor service, i have to collect from your so called office
