Appalling customer service

So yesterday the 11 April 2021 @ ackermans maponya @ 12:40, I experienced the most disgusting treatment from a cashier who was working @ the first till, as i was standing in the que to go pay for my items, I noticed those bowls they have with lipstick & nail polish then started looking in the bowl to see what colors they had, i was interrupted by a call which lasted exactly 20 seconds but was verbally assaulted by this particular cashier for holding up the que even though I had already asked the customer who was behind me to pass me as I was looking through this bowl, the cashier was behind the counter screaming at me who was on the phone to move out of the que, i ended the call to respond & tried to explain that I am just looking for lipstick & got interrupted by the call but by then the rude lady wouldn't listen to me instead responded by saying "yini sisi uyalwa" in a very threatening tone, as if that was not enough she continued with her threatening remarks talking to the customer she was serving, when I responded thereafter this cashier continued with the rude arrogant behavior saying "angikhulumi nawe" at this point I was furious that not even her colleagues or superior was intervening or calling her to order & i stormed out of the shop, I am appalled by this treatment & seriously question if Ackermans does in fact train their staff in customer service, conflict resolution or simple courtesy & etiquette. I unfortunately did get the name of this woman but plead with Ackermans to train the staff @ maponya mall.
