Bad service from staff and management

I went to pick n pay trade Route mall today and got such appalling service and disgusting attitude from a staff member called Eunice and her manager Irene. I picked 5 items and the quea happened to be terribly long and slow. I then decided to go pay in the kiosk area as it wasn't busy. Eunice kept on passing by and passing comments to her colleague about my items but did not say anything to me, when it was my turn to pay she said she is not going to assist me as I'm not buying anything from the kiosk area and I must go back and join the long quea(for 5 items) . I then told her there is no way I'm going to join another quea after having stood in the kiosk area without anybody notifying me or communicating that I can't pay in that area. She then walked out and said she is going to call her manager Irene screaming out to me "I can see from your face that you are a fighter" in a store full of customers. I had not even asked her to call her manager but She came back with this manager who is just as useless as her staff member. Irene told me I'm not going to be assisted, without greeting me or asking me what my concern was or what the issue at that time was. Her facial expressions was not even that of a person in authority or Intrested in hearing what I had to say as a consumer. I asked to speak to her manager and she said "go to customer services if you have a problem". I refused and asked her to go call her manager for me and she pointed out to a white guy, his name is Marius. When I spoke to him he didn't even have time to listen to what I was saying and I could tell by his body language that he wasn't Intrested or was in a hurry to get somewhere. His response to me was "il ask them to assist you but you must know that I'm doing you a favour", which I found totally unacceptable for a manager to say. He then pointed at some tilll and said I must go pay there...without apologising for his employees bad service, nothing... Eunice continued being rude towards me in front of other customers and none of the management team said anything. My main question in this is why people with such bad attitude towards customers are even in the service business. Management in store should be there to rectify such behavior from their staff and ensure that customers leave their doors satisfied but Marius just didn't care.

I always shop at pick n pay in Sandton, The Marc and I have never been turned back at the kiosk area for wanting to pay for my Goods hence I fail to understand why the process should be different at another pick n pay branch.
