Please UNISA stop using these guys, they suck

So, I've been waiting for my study material to be delivered since 25 July 2017. As per myunisa parcel tracker, my package was sent out for delivery on 25 July. It is now 10 September and I still have not received it. CAN YOU BELIEVE IT! Numerous emails ro skynet as well as unanswered phone calls, and no one is bothering to let me know what is up. Please UNISA stop uaing them. We are paying for a service that is not provided. So many students are complaining about this. Worst service I have ever experienced. And we are now at that point where it will be useless if my study material arrives now. As all assignment were already due and the exams start in less then a month. So thanks skynet. You guys are useless.
