Hi,

Shipment was initiated on 17th Dec from Ranchi to Bangalore. The same was booked under urgent category. Till today (10th Jan, 2019) the same has not been delivered.
Whenever I am connecting with Customer care, they are not able to provide any information. Each time they are saying, the product will be delivered today.

The document is very urgent. Please help here.
