false advertising and **** customer service

So at the store at the boulders mall, false advertising. 3 long sleeves for boys at R130 when I get to the till they say its not coming up. Is that supposed to be my problem?? The guy asks the lady next to him for help to override or something. She said straight in her language she is going on Lunch. What **** service is that right while I am standing she probably thought I wont understand what she said. This guy wanted to further waist my time to go check the skippers. Nobody said anything about the price. I asked for that ladies name he pretended not to hear me. I remember that Loraine came a did the override. I work in customer service and the service provided at this mall I am appalled!
