Biggest Courier can't deliver small package

I ordered a gift from Durban, left Durban on 28th of November. Delivery was said to be 24 to 48 hours. On the 29th I called the call Centre and was told that it was received at 4h30 in the morning at Johannesburg depot. I was told it would be delivered the next day. I called again on the 30th to confirm delivery time. I was told that it will definitely be delivered on the 1st of December. That's 72 hours later than promised by supplier... I called today, after over an hour I finally got hold of someone at Dawn wing. Just to be told eventually that it will be delivered on Monday the 4th of December. That's unacceptable... Eventually after passing the buck over and over, dropped calls and arrogant staff that promise to call back in 5 min just for me to have to call 30 min later to find out where my stuff is? Then I'm told it's at the third party delivery company, when I call them they have no idea what I'm talking about... Then another call to dawn wing, just to hear it has never left the Johannesburg depot. I was **** to so much today by people that do not just want to take responsibility for bad service. Now apparently it will be delivered on the 2nd as Priority package. It's rediculously pathetic, how can such a large reputable company make such a flop of something they claim to be professional at?
