Blue Dart Express — shipment delay in correct pin code

Address:

Kolkata, West Bengal, 700019

I was supposed to receive shipment with awb no [protected] on 13 jan, 2018. But now when im tracking the status its showing as wrong pincode given, shipment redirected on same awb. Whereas its a valid pincode. Its an important document for me. Toll-free no does not work as well. When will i receive my document? The courier people didn't even call me to know the location.
