Countries refuse to deliver to SA because of postal service.

I ordered a package many months ago to hopefully be here in time for a show I had to perform in. I made sure that there were at least 4 months when the order was placed as I know there is no service at the post office. I tracked the parcel which landed in JHB international on 8 August, which still gave me a lot of time to get my parcel. It only left JHB international on the 8 Oct!!! and then it never arrived at the next stop which was supposed to be Tshwane post office. I contacted the post office and they blame everyone else instead of taking action and finding the parcel. Apparently, they can't help me because there is no Bag number, The tracking number has become null and void. With their long fingers, they have probably dipped into the package and helped themselves. What else does one expect from our post office? It is astounding that they still exist. If they did their work they would not have to strike for more money as the people would be using their services instead of trying to find any other means to get their goodies instead of using the post office. So many countries are refusing to deliver to SA because of the poor postal service.
