Rude/appalling serive

Today I went shopping at Pick n Pay Dobsonville mall and was confronted or rather experienced an extremely bad service from an extremely rude till operator. This woman doesn't deserve to be part of the organization her attitude is very toxic for the business. Her name is K****tso Sekhodiso, she actually shouted at me to the top of her voice in front of all the other customers including her senior/supervisor. The reason she was rude to me was that i had actually put my 3 items on the counter already and she says I should have waited for her to call me instead of me being forward like that. When I reprimanded her that she cant talk to me/customer like that, she then threatened to skip me and promised me to just leave me standing like that while she assisted the customer after me. She called me all sorts of names and when I reminded her that I was a paying customer nd paying her salary, she told me she doesnt give a damn with the R75 that she's getting at Pick n Pay. When I finally left the counter as if that was enough she lastly told me I should go and do my hair instead if coming to be a nuisance. My concern is poor management at these township stores, the staff behavior is pathetic towards customers and they never will greet you, and worse they won't even pack your stuff, expecting you do it yourself and management does nothing about that sort of behavior. Now all this burden of poor management gets to be carried by us paying customers. If Pick n Pay is not going to take further steps for such uncalled behavior they will find themselves without a business in most black areas.
