Poor poor service

I've send a parcel on the 8th of Aug, and as of this morning, 24 Aug, IT IS STILL NOT AT ITS DESTINATION. It usually takes 4 days. So it was delivered at the wrong postnet on the 12th. Simone in Sandton/Randburg postnet signed and received it. After 3 days I had to search for the parcel. Postnet itself couldn't notice, nor did clever Simone that it was delivered at the wrong postnet. It was redirected then... handed over to a 3rd party on the 21st ONLY.. HOW REDICULOUS IS THAT?! After countless phonecalls and emails, I'm still waiting for it to be delivered and all that is being said is sorry..
