Safety compromised by driver

I ordered from Steers Lorraine and my order was delivered by the rudest man on earth. He even exchanged words with the security guard of my complex. Firstly he rudely tells me he used his own airtime to call me when I told him he cut the call as I qas about to tell him to wait at the complex gate for me. Then he said he does not carry cash and only has a card machine, when I told him I selected cash on delivery he said it does not state on the receipt he had that I will be paying cash. He then snatched the R200 note I had in my hand and chased down a car coming into my complex to ask for change from the driver. He got 4 R50 notes. I had to pay him R150 because he did not have change. All this happened with him shouting at me and every person he saw. He did not appeared wide eyed and jittery. I felt uncomfortable and unsafe.
