Food Poisoning

I ate Burger King from Lake View (Soweto) I've been vomiting since yesterday right after eating it. I also have diarrhoea because I've been going to the toilet a nemours times. I think the meal might have had food poisoning or expired "Whopper" I want to be compensated because I had a occasion to attend to but I couldn't because of the meal I had at Burger King "Whopper meal." Please do something about this because I had contacted them and they promised to give me a call back but they never did.
