Selling year old food is healthy risk to be carried by me

I bought 2 Dewfresh 1 litre fresh milk. The first one I allocated for use quickly got expired and i couldnt understand that. The second one I have just opened shows the Best Before: prd -30/04/2021; BBD -30/11/2021. Pick n pay Benmore is subjecting humans to possible toxics and defect food. This may affect not only the buyer but the whole family including children. Customers are prone to this illicit trading of out dated food, risking healthy status that is too expensive to maintain its bill. I will be anticipating engagement in a form of money back to all customers who bought milk around 29 - 30 September 2022.
