Food poisoning

Last week and Sunday 20 September my mother and 5 of her friends went to the buffet at cattle Baron plattekloof. They enjoyed the buffet however later that evening everyone who ate had bad food poisoning. Cramps, diarrhea and throwing up. My mother was so weak and was up the whole evening. I called the manager they next day he was not interested and advised they must have eaten something else. They did not eat anything else... They are pensioners and all over 70 and they were terrible sick... It is unacceptable and you need to do better.
