Bad customer service

Received worst customer treatment from one of their staff Pick n Pay in Elspark. There was price on one of the items we purchased, but when we got to the till it was R11 more Than what it was on the shelves, but the merchandiser was si rude when I was querying it, and Agnes refused to give me with the price it was merchandise at, saying it's a different flavour n weighed more than the price merchandised at. It was the attitude that was unnecessary,
