Expired bread

My sister and I bought bread at Pick n Pay Vangate mall yesterday evening. We didn’t check the bread as we trust Pick n Pay with hygiene and good stock. She took 2 slices without noticing and when she was about to go for the other 2 slices she saw that the Blue Ribbon white loaf of bread had moulds/fungus which she and her boyfriend had already eaten 2 slices each. We are in disgrace and utter disappointment to get something like this from a well known store like Pick n Pay. My sister is now sick with a stomach bug.
