SA Worst Office

I ordered an item and received my tracking number. The post office tracking section of the site does not work 95% of the time. That in it self is a pain but when it had worked once, I found my package has last moved 25 Jun 2018. Now it states on the site that should you have queries there is a number to phone and an email address. The problem is that I gave up after holding on for 45 minutes waiting for an operator listening to how "Important my call is". As for the email address; I have sent various emails over several days and have as yet not received a response. To top it off, if you want to lay a complaint, you need to send a mail TO THAT SAME EMAIL ADDRESS. How utterly useless. My package is insured, but is apparently impossible to get a hold of someone to claim or get a proper update.
