Incorrect signage and arguing with the client

Yesterday I purchased a dress in the above store for my wife, on walking out I passed through mens footwear. I saw a sign that read, \ 50% off the last original price.\" I found a pair of grey Nike flip flops that were originally R299 and had a red sale sticker for R209. I asked the consultant if the mark down would now be R105 or R150. He rep**** the red sticker was already 50% off. (shocking) I asked him if he could work out the half of R300, he then walked away from me. Another female consultant came to assist me, agreed that the price didnt match the sign. Sh scanned it at the till and it still scanned R209. She then called the manager at my request. He the tried to explain that it doesn't matter what the sign said there's a read sticker on the box so that's that. I then asked him to read the sign and work out the price according to what the big red sign said. He agreed a should be R150 but the staff made a mistake with the sign and also he knew me from working in the mall previously so I must accept the box price.<br> <br> What does me previously working in Bayside mall have to do with falls advertising and a manager that has know knowledge of the NCA?
