Rotten 5kg White Star Maize Meal....

Im so disgusted.. I bought 5kg white star maize meal at Pick 'n Pay (Liberty Mall in Pietermaritzburg). Today I opened it as I felt like eating sour milk (maas and uphuthu). At first I thought maybe something got into it (mosquito) but no it was small (kind of worms) and black insects. Yet the expiry date is 07/2025.. This is not happening for the first time. The other day was ice cream that had horrible taste and some ice in it (like melted ice cream that was frozen again)
