Stinky and bad service from Jet Sontonga Mall

I had a bad experience of shopping at Jet Sontonga Mall,I bought a school shirt priced R55.99 but was charged 89.99 when I queried that I was told its 20% of the person who wrote the price made a mistake,then I told them the prize I see it's what I'm going to pay. Was then told they will call a manager who came and said nothing to me but spoke to her staff. Then the cashier had to give me a difference but her attitude was like I asked for her money to pay for my items. She's a cashier she's supposed to have a heart for retail,I'm a manager where I'm working if it was my staff acting like that towards the customer we were gonna have a serious talk. She then told me told that she's going to the door with us cause we must leave the slip,my question to her was why should we leave the slip what if we want to return something,then with a stinky attitude she said I told you that you can return without a slip which I find funny as the slip at the back is written you need to have a slip for a refund. And the way she spoke like really is this the kind of service Jet Sontonga Mall is rendering to customers. This need to be attended to or I'm taking it far ,really cant ne treated like that while I'm spending my money it might be at the location not in suburbs but some of us know our rights,we know how to be treated at the store. The cashier in question is Pinky Dlamini she really need training and I need and apology from them or I'm going social media and far with this.
