Checkers in kosmosdal sells expired food, i am literally sick from eating their things

Have bad history with the store. Not so long ago I had bought a peppermint chocolate dessert at the dessert section of the store, I got home and opened up the dessert but it smelled off and tasted like what expired milk would taste like. I told me mother to confirm and smell whether I was exaggerating or not and she indeed told me it wasn't right to eat because it was expired. I then checked the desserts expiry date and it was expiring the next day. So my mom insisted that we go back to Checkers with the receipt and get a replacement of the dessert at the store that wasn't expiring the next day. We went to Checkers and when I got to the kiosk I spoke to the ladies at the til and told them what my issue was and asked if I could get something else instead or another one of the desserts that was in the right condition. I went to the section I had bought the first dessert at and all the peppermint chocolate tarts were expiring the next day as well so I went back to the ladies and told them I couldn't get one because they were all expiring the next day. After telling them they decided to go take the desserts off from the section and throw them away and I got my money back after that and was so disappointed.
