Unhealthy food

Me and my colleague went to Pick and Pay Silverwater Crossing on the 29 December 2016, I will never forget the date, we used to buy lunch there, on that day we both bought russian and chips, and few hours later we started vomiting and had diarrhea, I had to be rushed to Montana Hospital by my colleagues as they saw that I was about to pass out or die, I was left with Hospital Bills to pay which I am still paying now, and I just wonder if they do check whether the food they sell to their customers are safe or not, my colleague did not end up in hospital as she got sick at home, but was also in a bad state, the sad part is most of our colleagues came back and told us they experienced the same problems as they don't sell fresh food.
