India Post — No update on delivery of consignment.

My article, consignment no ED[protected]IN is stuck in LGBI AP TMO Guwahati since 15th July. It shows that the consignment has been dispatched from LGBI AP TMO on 15 July but there is no update on the India post portal since then.
5 days and counting and no update whatsoever.
The consignment is really urgent. Pls help
