Bad Service

On 2 November I walked into OK in Thornton to purchase flour and coke. The flour scanned R 48,99 but the shelf pricing showed R 36,99 , I asked the cashier about the difference, she then called one of her colleagues, he said “ the difference is too much “ he refused give the shelf price and told me to return to the store in morning for one of the managers to decide , he left me at the till , changed the shelf priceI . I asked the cashier to call the man Ijust spoke to , she refused and told me to call him myself I then walked to the back of the store asked him for R 36,99 shelf tag , so that I can take a photo for proof when I return in the morning. He refused , I asked continuously he told me that he already threw away. I told him my right about paying the price I see . The cashier refused to give me her name , or the name of her colleague. Or to write down any proof that I’ve been in the store and that they destroyed the R 36.99 price tag. It was such a bitter experience, no one on shift to make a decision, no customer service or etiquette. Im so disgusted .
