Worst Service ever Tops Spar Sunderland Centurion

I have had the most horrible experience ever with a cashier Lesego at Tops Spar Sunderland in Centurion. Few months ago I had the same experience with Lesego. I got there, friendly as usual greeted her but she ignored and continued to have a conversation with the cashier next to her and that cashier's client. Yes she was scanning my things but ignored me like I wasn't even there. I asked her why doesn't she acknowledge my greeting, she rudely said she didn't here me. I told her was gonna report her attitude and ignoring a customer infront of her and preferred speaking to her ****orker and her customer. I got home and decided not to do it. Iv been to the same tops couple of times and I made sure I don't go to her till. Today at 13h04, I went to tops and she was the only cashier and I went straight to her. I greeted her, she kept quite. I asked her why don't you like greeting back. She said "I didn't hear you" with an attitude again. She got up and pointed her finger at me and said "wena you have a problem with me", she went on and on and I said Lesego, this time I am gonna report your attitude just scan my things I need to be somewhere. She stopped scanning my things and called her Manager. I continued to say scan my things I wanna go home. She said wait right here let my manager come (screaming). Her manager came, she pointed her finger at me and said to her Manager, "this one has a problem with me", and went on and on...I said to her Manager, can I get my things scanned I wanna go home. Lesego went on her voice going higher. Her Manager asked her to calm down and not to talk to me like that but she went on and on. She went ahead telling me I must remember we don't come from the same families, I asked her again to scan my things I wanna go home. But she continued and mentioned a med lemon incident that I know nothing about so it seems she fought with someone else over Med lemon and she is confusing me with that client. This clearly means she has preferences when it comes to clients. She is so rude. Her Manager even told her that look the client is not even screaming at you, scan the customer's things and let her go. But no she wouldn't back down...I want something to be done about this and I want feedback. She is so so rude. Imagine you want to be served you are standing in front of a customer service rep, and she ignores you and prefers a convo with a cashier next door. That was my first interaction with her. She lacks manners and she looks down on other customer's and probably has her own Preference
