Hector the Angry, Cursing Monster security guard

I was at Pick ‘n Pay yesterday to get a few items with a friend. On our way to the till point a Hector(security guy) walks up to me while l’m having a sip out of my soda with my mask pulled down under my lip. He tells me to put my mask on in a very rude, aggressive and intimidating manner. I just responded to him politely to leave me alone and walked away from him. He came chasing after me threatening and intimidating me on how he was going to beat me up. I told him he must keep his social distance and to not talk to me in that manner of swearing and cursing my mother. I then told him clearly we are not on the same level and class and it seems he doesn’t value his job. He told me he doesn’t care of his job but he will beat me up. Then his colleague lady security called him by his name Hector continuously to leave me alone. I then proceeded to pay and approached the store manager and he later called the head of security to intervene. What scares me the most is what would have happened if he had attacked me physically since my friend and l were armed. How was l supposed to defend myself against a person full of so much rage and anger I even explained this to his superior (Steven). Steven said he will look at the video footage.
