Mislead at Clicks, Sasolburg

I visited clicks, Sasolburg to get a Kair serum for my hair. The price on the shelf was R55, when I got to the till it said R79, I told the cashier that in the shelf it says a different thing, her and I went to the shelf and there were 3 R55 price tags and not even a single R79 tag. She still insisted that I pay the R79. Poor customer service and misleading! 🚮
