Remove stock you no longer sell

I went to the hyper this morning, thinking my changes of finding the product, is better at the hyper vs a store. I was then told the product only sells via the Checkers60 app. The clerk helped me to download the app,v& together, we tried to buy the product. After checking their systems, I was told the product has been discontinued. I told the clerk it's unacceptable that a discontinued product is still marketed whereas it should be removed. It gives a false impression that the product is still available. I'm referring to the Simple truth, broths products. Kindly remove it from your available products as it's misleading, thanks.
