Noleen treated me as if I was trying to cheat

Good day<br> We had a pricing problem in Pick'n'Pay Nonesi Mall, Queenstown this morning. The shelf price was R12.99 but scanned as R20.99.Cashier send the packer to check and I showed her from where I took it. Cashier called the supersisor Noleen.<br> The moment she was called to make the correction she was not in a good mood. She said she has to verify it herself ( it was verified by the packer before) Being a sunday and first if the month there were lot of people in queue and they started shouting at me as if I am delaying them. Only four tills were open. Noleens attitude was that I was trying to cheat or something like that. <br> Infront of all those people I was made a ***** or a fool as if it was my mistake that I took the product from a different place. This kind of an attitude was unlike pick'n Pay staff.
