Blue Dart Express — not delivery of packet

Address:

Patna, Bihar, 800002

My packet was send from meerut. Its no is [protected]. When i tracked it, showing that packet arrived in patna two days back. Whole day it was showing that packet is out for delivery.in the evening it showing that address is untraceable and land mark required. Today it went to service centre. They told me that packed will delivered to you at given address. But no body contacted me. Again in the evening showing address is untraceable and land mark required. What kind of false conpany.
