Rotten Purity

Bought purity food at Clicks and Dischem at the same day, Went home and packed out, Next day I gave my baby a sachet and it smelled off I threw it away. Took a other Sachet and it was fine. The next day I took another one and was completely rotten. I took photos and video, Complained on FB Messenger and showed Purity the rotten food 9th January 2025, Until now no feedback, they read all the messages never respond, Email no respond aswell
