False Advertising - Special's but supplier didnt provide stock

You are advertising falsely. You had a special 08-10 April 2021. 3 x frozen meals for R30 (Mac and Cheese, Chicken something and beef lasagna) Fish Hoek branch only received stock for Beef Lasagna. You cannot advertise something you so not have stock off. When i phones the head office, they advised this is all they received from the supplier, then you should wait to see what you going to get before you advertise falsely. The same with the samosas that were advertised. They only had veg flavor, although 3 different options were advertised, but no stock was received. Or give the customer a rain check so that they can get the items when you do get stock. But dont promote or advertise something you are not even sure if you will receive it from your supplier.
