Expired Fruit leads to me child falling ill

I am a regular woolies customer and do most of my shopping at woolies. The woolies store that is based at the airport is so convieniant for emergency stops as it is close to where i stay. Last night, 11 October 2017, i purchased quite a few things from them including fruit for my 8 year old son. He had insisted on having fruit for supper which resulted in him being extremely sick all night! This morning, i couldnt understand why he was that ill and my GP advised i think about what he had eaten. to my horror, the fruit i had purchased was all expired!! How on earth could you sell me expired fruit? I have taken pics of my slip and the dates on the fruit. i demand that someone get back to me on this matter.
