Bad service

I was at around 11am pick n pay birchleigh liquor buying red square energiser. I saw a price of R114. 99 and at the tills it scanned R129. 99. The cashier there went to check the price and it and it's was R114. 99 red square pink and under that there was a price of R129. 99. Then I asked the cashier how are you going sort this out? She show me a supervisor and I asked that supervisor she didn't even looked at me she was busy on her phone and said to me the price is 129.99 thats it. I didn't mind paying that R129.99 but the attitude of that supervisor it so pathetic and roting to the core and I end up not paying for it because of her attitude. The cashier was doing the best to sort this I wish she was the one who was the supervisor. I normally come there to buy but after today I think I will take my business somewhere else.
