No Stock!!

I would just like to know why Checkers is having specials, but they have no stock! We went to Checkers on Sunday to purchase the 1kg Rama tub that is on special for R29-99, asked around, sorry no stock. Went there on Monday no stock, went there on Wednesday, no stock. I enquired when the stock was coming in as the special is ending on this upcoming Sunday, no sorry we are not going to get more stock. Now as far as I know according to law, if you have a special you are supposed to have enough stock. So what now Checkers! How are you going to rectify this. I tried to communicate with you on your app, but no matter what I tried it would not accept my phone number.
