WRONG PRICE!

On the 06/07/2015 my mother went into the store and bought an item from Truworths.. when she got to the till the item scanned for more than what it was on the label and the cashier said she cannot give it at the price on the label because it scanned more.. my mother then said she is not paying the scanned price because that's not whats on the price tag and the cashier then called the manager who had the same pathetic notion of my mom having to pay the scanned price. As a consumer she has the right to get it at the price she sees and what was even more disgusting was that indirectly they made it seem as if my mother changed the price I mean really - so she is supposed to walk with a swing tag gun in her bag even though the description is the same? The manager didn't even have the decency to apologise and my mom had to put up a racket first before they actually assisted her with the product.. my mom is a loyal customer at Truworths, this happens quite a few times with her even at other branches too especially promenade.. The managers must make sure the shop assistants prices things correctly, IT WILL SAVE THE CUSTOMERS THE EMBARRASMENT!!!!! if no response here I will take it further!
