KING KORN FINEST MABELE WITH WORMS

On the 6th of January 2020 i bought king korn fine mabele from Shoprite and empty it on the cereal container on Saturday i prepared it for breakfast when we were eating my child found worms , and i went to check on the container only to find there is a lot of alive worms . My dilemma is that i already threw away the packet and the till slip i can't find it . I will never ever consume that porridge , how can they supply something as filthy as that , it a disgrace.
