Food Safety Reports: German Doner Kebab (GDK), High Street, Southend-on-Sea, UK

Just Eat order of GDK arrived cold but I ate it as I was starving. Later that evening I was really ill for 24 hours. Even in store the food is never that warm. Are they trying to save on bills?  | Symptoms: Nausea, Diarrhea, Vomiting
