Document booked by Speed Post from Kolkata to Ghaziabad on 5th June. 7days is gone, still the document is lying at Kolkata AP NSH (Airport sorting hub). Complaint no 2000281037 is registered. Nobody at the customer care also is able to answer. I fail to understand why it is not moving from Kolkata to the destination when both flight and train services are operational from Kolkata to Delhi. Can somebody respond to the complaint and update regarding delivery?
