Bad attitude from Nontobeko

Good morning, i am very disappointed with the service i got from Shoprite liquor at Diepkloof Zone1. There's a lady by the name of Nontobeko i think she is a supervisor. Her attitude is disgusting. On the 23rd of September i went to buy drinks and i asked if they have Simba chips on special since i saw them at Shoprite. The lady who was helping me said she is not sure but she will scan and check for, unfortunately they were not on special then i asked her to cancel them cause I'm not gonna buy them, she requested thee Nontobeko to cancel for her, she said hai maan nisebenza uku cancel today kunini(meaning) that's the only thing you doing today to cancel. This lady explains to her that i thought the simba chips were on special, she why didn't you tell her that they not and i answered no sisi its because i saw them at shoprite she immediately said this is shoprite liquor we don't work as shoprite shouting at me pulling a face and i said okay its fine. On the 02 October the same Nontobeko shouting at he cashier because there's a customer who was told if she buys 6 wine glasses it will R70 hey that Nontobeko i work here its my first time hearing of that, and she turned to he cashier don't you know that we don't do that, she tried to explain but she didn't give her a chance to do that and left the customer just like that. She needs training all over again please, the tendency of shouting her colleagues in front of customers is very wrong, the way she attend to customer queries she is so unprofessional. She need to learn on how to treat customer. I'm very fed-up she think because we are at the location therefore we don't know our rights as customers. This needs to be attended as soon as possible please.
