Sour Ice-Cream

On the 11th of October 2022, after work i though it good too buy my kids each a cup of ice-cream as a treat because it is so hot. Only to find out once we got home that the ice-cream is sour, lumps and all included. And yes I can say this because my kids complained that the ice - cream was tasting funny and tasted it myself. Please do not serve more people sour ice-cream it is really unpleasant.
