Alitalia service

My spouse and I flew back to Johannesburg from Rome via Alitalia in September 2019. We both picked up food poisoning in Rome and my wife became violently ill. She vomited in the seats, the passage, two toilets and over some passengers. No help of any kind was offered by the service staff on the plane, despite my asking. In fact, a woman who had become ill for another reason, attempted to sit on one of vacant seats reserved for staff was not allowed to do so even though the seats were not used at the time and would not so be used for at least another two hours. She was obviously in distress and it took another 40 minutes for staff to call for a doctor who then sorted both her and my spouse out. To not render any assistance, to not allow a temporary seat close to a toilet thus forcing a passenger to vomit in her own seat amongst passengers and to delay calling for a doctor when such was obviously indicated, I felt was not conduct up to the standard that one expects.
