Deceiving customers

I often visit food *****s at the crescent, Umhlanga. A week ago, I purchased 3 kg cook.likeUTD potatoes for R80. I've been back there on Thursday and they had 5 kg UTD potatoes for R80 which I purchased as well. I opened the bag today n decided to use the so-called UTD potatoes which has been cooking for more than an hour now. Upon inspection of the bag, it says up to date and on the underneath, it says "cooks.like UTD. They are deceiving customers. We paying the price of UTD and getting *******. I called the store and spoke to JOY who promised that a manage will contact me within a few minutes and no calls yet.
