Impossible to get in touch with customer service

Absolutely impossible to get hold of anyone from domestic deliveries. Trying to track a parcel from Ct to Jhb. I have been advised that it has been sitting on the Jhb floor since 3 June with no movement or scheduled delivery date. I have tried to call numerous times (more than 20) and every time I am transferred to another person, put on hold and then cut off. I have called 3 different numbers. The main contact number directs you to a different branch each time (CT, then PE then Jhb international). I have also sent emails, with no response. I also tweeted and sent a facebook message (they don't allow you to post on their Facebook page). The call back function on the website also does not work.

It is absurd that it is so ridiculous to get hold of someone who can assist me.
