Disgusted client

Visited Kwik Spar Tops at Mdantsane City today and was disgusted with the service received from a cashier at Tops. I bought Four Cousins white wine because it had R89,99 price and when I get to the till it scanned R105,99 and I enquired with the lady she said that's impossible so I said am bringing the price. Came back with the price and she gave me a cold shoulder and brushed me off and said no this was an old price it was supposed to be removed so I asked by who because this is price that's there? She brushed me off and just said there is no-one to override this price if I don't have the R105, I must leave the wine. It's the way that she didn't show interest and didn't care to think that the same thing happened at Shoprite and the cashier didn't even argue he just called his manager and all was sorted and at Tops, I got the most ridiculous service am disgusted
