Bad service

I'm really appalled at the South African Post Office service. I've been trying to obtain proper details about the whereabouts of my package and either the telephone numbers supp**** - no one answers or when they eventually do, they have no clue as to what is going on. On the web it says the package is in Transit since the 4th already. The last time I called I was told that the package will take some time to come through due to it being Christmas rush which I completely understand. I called again today, being transferred and transferred to only be told that I need to send the invoice through as the package is still at Cape Mail and needs to be cleared. If I had received any sort of notification for this, of course I would action it immediately. I was given an email: [Email Removed] which bounces back. No wonder people pay hundreds of Rands with a courier just to get their package on time... I know for a fact that I will be using a courier next time I purchase something from overseas.
