Bad attitude

I went to Ackermans 836 I bought few items and I wanted to buy shoes that were marked R60 with a pen, when I got to the tills my cashier was Thapelo who said the shoes weren't marked down in the system however the till operator next to her by name of Granny gave me a very bad attitude that what if the shoes were marked by myself. I asked if as a customer I can do that? she said it is not her problem I can't afford the shoes. If that is the kind of attitude we receive at Ackermans it's really disgusting. Granny has bad attitude and bad manners. As I understand consumer protection act the price you see is the price you pay. Instead of all her bad attitude I believe it was appropriate for them to liaise with the manager. People like Granny they done deserve to be at the stores to help people all the do best is to show bad manners
