De shelving of stock in promotion - Consumer Complaint for Clicks Store - Head Office

On 3rd of January I saw on my Clicks app that the Toni and Guy XXL straightner was on Special, so I went into store on Monday to purchase it, when I enquired abt the stock, I was told that it was out of stock, I immediately phoned the 2nd branch in area and got the same response that it was out of stock,oh well I left my details and was told that stock would arrive today. But I also saw numerous posts on social media that all stores that claimed to be out of stock had hidden the stock in the stock room,and after numerous customers had mad a fuss they were given the stock, why would you do that. I have been to the stores today as well and still no stock, am I supposed to be barbaric in order to purchase something that you had placed on promotion. Very dissapointed I could only post 1 picture but I have numerous photos.
