Makro staff and their putrid behavior

On the 29th of November I had been shopping in Makro Arbour Crossing and had mistakenly picked an item and was at a till to pay. Only to realize that there was a mixup on the shelf and I had to change the item with the correct product. While my wife was standing at the till and the cashier, Lindiwe Sibiya, was gossiping with her colleagues about how im making her wait because I'm crying to pay R100. Failing to understand that it was not my fault but the fault of the staff who packed the shelf and mixed up the products. Further more, all the surrounding cashiers came to that till and was congregating and passing comments and making accusations in Zulu even though we are in the middle of a pandemic. This included the supervisor who also refused to void that product. These staff members felt comfortable enough to do this in front of my wife thinking that she does not understand Zulu. We complained to customer care and haven't received any feedback thus far. Is this the precedent you people set for your customers?
