Ace feeding us infested maize meal.

I bought Ace Maize Meal 10kg from Boxer in Klerksdorp City Mall. It was on sale and gladly bought it because in this economy of today we target sales, little did I know that my family's health would be put at risk. I cooked it today only and it was purchased around the 21st. As I was making the pap I realized that there were worms in the mealie meal as a result I had to throw it away. I did not keep the receipt I got when I purchased the maize meal as I didn't expect to experience such dissapointment, otherwise I would have gladly went back to the shop to request a refund and purchase another brand of maize meal. It's extremely disappointing to go through such especially from a company thats supposed to be reputable. I mean it's not the new kid in the block, so they should live up to standard. I was busy making supper for my family at home and ended up having to give them bread Intead. I feel that I should be compensated for this kind of inconvenience.
