Package stuck at post office

<p>I had a package delivered from Durban on the 19 October. When I checked the tracking number PE ********** 21ZA, it seems like this parcel is stuck at the WITSPOS post office and therr is no way to contact them as the number doesn't exist and the SA Post office customer service line just puts you on hold. How is a person supposed to receive any parcels? ! Totally disappointed</p>
