Pick n Pay Cashier extremely rude

A Lady cashier at. Pick n Pay Midrand Boulders Shopping Centre, by the name of Tshifhiwa was extremely rude to me today, this is after a teller next to her experienced problems and moved to another till and left me standing there without assistance, I then asked Tshifhiwa who was going to assist me and she was extremely rude, she said where does she come in, as to whether I get assisted or not its none of her business, I then called her Supervisor Mukovhe who tried to call her into order but she also disrespected her by telling her that she will never stop talking if acustomer is talking things that are out of order which is way out of order. Her Supervisor Mukovhe had to ask her to assit me and Mukovhe apologized, Tshifhiwa continued to show faces of disrespect until I left the store.. I do not think I will ever set foot at Pick n Pay again after this..
