Extremely unprofessional staff and late delivery

My study material had been despatched on the 11/8/19 and out for delivery since 13 Aug 2019 and I have still not received it.I had sent multiple emails to which only this morning I get a response by a male from despatch telling me that I should pick it up from a location I am not fami**** with.I told him I do not know where that is and I have no transport, to which he responded AGAIN that I will need to pick it up at a certain unfami**** location. I told him that if he does not deliver my books I will send screenshots of the conversation to UNISA as well as the Ombudsman. He responded with a voicenote(which I have in my possession) saying that he is doing me a favour and that his car is in for repairs and then he asked for my address.

This is extremely unprofessional as we as students pay our full fees and choose the 'courier service' that Unisa offers so I do not understand how we are being done any favours by skynet. Also, I stay alone and I feel unsafe now after the abrupt interaction.I have 2 assignments due this week and I fear that I will end up failing the semester due to late compulsory assignment submissions because of not having received my material.
