False Advertising

So today Sunday 12 September 2021. Me and my colleagues see an ad from KFC 50/50 deal, a family treat for R100. We can not order it. It just shows an error message. Alright we call the customer care they ask us for a screen shot which we now all have of the deal. But they say that deal does not exist which means they are false advertising deals online that they never own up to or even explain why it is there. Now the deal is taken down.
