Process followed on products not barcoded

On Monday(18/12/17) i went shopping in pick n pay hyper in montana(pretoria).i wanted to a christmas decoration board but it didnt have a barcode on it and it was the only product left and there was no information on the shelf relating to the product.the staff member that was assisting me went to enquire with his supervisor on the price, i followed him and he was told that it was R129 without any verification on the accuracy of the price.i then paid that amount even though i was not happy about the entire process because i feel i have been ********** and disrespected as a loyal customer.yesterday i called the customer care and was asked to send an email with a picture of the item i was quering on, i then sent the email and got a response that they will respond to my email shortly.i still have not heard anything from them, im really upset.pick n pay im so dissapointed in you.
