Delayed services

I've been trying for almost a month to get hold of the South African Post office.. the phone just rings and rings. I've gotten through once a few weeks earlier but after that, no answer. I'm trying to track a certain parcel from Overseas - which I ordered in late December last year. the company that I ordered my parcel from is under the impression that I've received my parcel. I also called my local post office and they said the system shows that, it's still at the airport at customs, but another tracking service said I needed to call my local post office... So no 1: The parcel seems to be extremely delayed. 2: Systems are not updated 3: I have to constantly follow up for this parcel - but my calls aren't answered. Not alone is SAPO's services delayed, but the companies that are suppose receive and send parcels don't know what's happening either. I've paid a lot of money for this parcel and I'm not happy with the feedback that I've received
