Sad day when we cant even collect our own post...

I ordered a package via post from Port Saint John's on 25 May 2018. The tracking states it is still in Mthatha Hub. I called them and they insist it has been in Witpos since 30 May already. I expected delivery by Friday 8th June, two weeks after it reached Witpos, but still nothing. It was a birthday present so on Friday 8 June i sent someone to collect but the post office couldn't even give me my post if I fetch it myself. They have not even opened the "bag" my package is in which is why the tracking number isn't getting updated on the web as it hasn't been scanned this side yet... I have called for help but 3 of the times i was put on hold until the line went dead, a few times the person just put the phone down while im talking to them and I have yet to receive a response to one of my 5 emails to their customer.services. I have complained on their FB page also with no response as yet. This is not right that they are preventing us from getting our post. My father went to Witpos and told me that they would not even give a lady that tried to collect her medicine to her either. This is ridiculous. I am going to see what kind of legal action can be taken against government establishments like this as this is not right!
