India Post — non delivery and missing of postal item

Address: Kamrup Metropolitan, Assam, 799014

Ragistered postal parcels to this state are never delivered by india post, even the parcel if not delivered dosent come back to us, i have sent many parcels in past few days to guwahati region via india post but none are delivered, very frustrating, there must be deep investigation as to why these govt guys are paid for, not even phone they lift[protected]
