Maggots in my Cereal "Morvite "

I have had one of your cereals "Morvite" it is infested with maggots and webs ???????????? this is the second time. In 2017 I bought one of your morvite at Spar Rink Street and all they could do was return my money . They didnt even appologies as if I went there to buy morvite with maggots. Now I bought the same brand in Morvite ar Shoprite, it has sticky maggots and webs that are slimy in your mouth. I cant even keep anything down from the disgust
