Very disappointed with how clicks handles their so called errors...

So 2 weeks ago clicks loaded on theirs clicks club cards 2 * 2l clicks bubble bath for R25. So I uploaded the deal and when I went to clicks I was told that it was uploaded by error. It was suppose to be 25% off. Not my problem I told them and they refused to give me the bubble baths. So today 16 December 2020 I see the same deal is loaded on my clicks club card. I called the customer service department and they told me it was an error again. My sister stays in the vaal she went to clicks and got them for R25 for 2 and immediately the manager took the bubble baths off the shelves. Why did other people get this deal and yet I didn't. Maybe I forgot my rights as a customer cos I know that the price I see is the price I pay as per consumer rights act. How can they do the same mistake twice and how is it my problem as customer. Honestly I am really disappointed with the way this whole situation was handled. I hoped you handled this situation fairly. Very disappointed
