Mouldy Cupcakes

I bought cupcakes on the 11 Sept 2015, with expiry date showing 12 Sept 2015, however upon opening them I found them extensively moulded, unfortunately was a bit to late, my so had already consumed 1. Half an hour later, he was as ill as a dog, vommiting all over the place. Needless to say, after complaining all checkers had to offer was a lousy refund. Totally disgusted!!!!
