on board food posioning

food poisoning on flight SA235 LHR/JHB 28th Feb 2019 , I experienced the worst flight of my life . I took the fish option for dinner after awhile my tummy was so unsettled with intense stomach cramps i started feeling extremely hot and i couldn't breathe. i called on a flight attendant which took forever by the way, and i asked for a cold towel which she said they didn't have and the best she could do was bring me ice i tried to explain that i couldn't breathe and she insisted that i stand up i passed out twice , once on my seat and a male flight attended was called to help wake me up .i woke up while i was being pulled or i can say dragged out of my seat i passed out again and only came to life after and found myself at the back of the plane . the passenger who was seated next to me happened to be a health practitioner was the one who helped me through this nightmare he made me take lots of water to help flash out the toxins and another passenger who was also a doctor checked my pulse and came to my aid .what the flight attendants did was to give me oxygen and make me fill in my details in a report , i threw up and had diarrhoea plus shivers all from that meal i had while on the flight, am still traumatized till now . i don't know if SAA does refresher courses on first aid cause whatever they had in they're medical supply kit was of no use or help .so if those 2 individuals were not on board the flight i took i don't know what could have happened to me because importance was placed on the report rather that my personal well being .
