I have couried a consignment on 20th january and i'm calling customer service executive in 25th for tracking my consignment.
But that executive put my on hold for more than 5 mnts afterwards they are not responding my call also still now i can't track my courier.
Take an action against non delivery of my consignment on time and irresponsible executive.
