IWISA Maize meal having white worms

I bought IWISA maize meal at boxer Mall of Tembisa on the 16 March 2026 and on 17 March 2026 afternoon when i was about to cook supper for my Family discovered that it had worms. and when i called them they telling me about pictures and out of frustrations i threw away the mealie meal and complained the only thing they want is pictures and they not concerned about the health and what if other customer are busy consuming it without notice and the worms are white and not so visible
