LEGiT Hatfield refuses to sell item at the price on the tag.

I had such a bad experience at LEGiT today (25/09/2021). After hours of searching for the perfect heels from shop to shop, I finally found them at LEGiT here in Hatfield and at a very reasonable price of R149.99 and in my size which I struggle to find in most shops. The heels were reduced from R349.99 to R149.99 using red stickers (the reduction was done to the entire collection of the heels). The R349.99 was crossed out with a black pen. However, when I proceeded to pay for the heels, I was told that the 'system' says the heels are R249.99. I told the cashier that I was not willing to pay for a price that was not indicated on the item in the first place. She removed the red reduction sticker and said there was nothing she could do. I insisted she called her manager, who came and told me that she is not in fact the manager but the assistant to the manager and thus cannot help me as only the manager can do so. I explained to the assistant manager that I needed the heels for an event I'm attending later on but was not going to pay the new price for the heels. Mind you it is a Saturday and I'm desperate to get the shoes as soon as possible. So I asked her how she as the assistant manager does not any authority to deal with such matters and was quite rude telling me if I wanted the shoes at that price (R149.99) I must come back on Monday then the manager will be there. This was crazy because I told her I needed the heels for that evening and as I was speaking to her, the cashier went to remove all the red (R149.99) reduction stickers from the entire collection. So how was I supposed to come on Monday and want to buy the shoes at a price that was removed? It didn't make sense and I had wasted too much of my time going back and forth with. So I ended up having to buy the heels at R249.99, like I said I needed the shoes. But I feel very cheated on this matter and given that it is their store policy to sell at the price indicated on the item.
