Flight attendants

I was on flight FA 303 on Saturday the 3rd of March which was scheduled to leave at 16:55 but as we were reversing unfortunately an incident occurred where we needed medical help ASAP ( A gentleman in his late 50's / 60s was having a heartattack ) myself and a few other people on the flight attended to him and called for help as he needed CPR and for them to stop the plane , my complaint goes out to the staff on that flight as NON of them knew how to do CPR (please tell me how you have a senior air hostess or in that matter any air hostess without any form of training?) - they were in more of a panic than any passenger on board ! What happened if we were in the air ? Or god forbid if it happened to me ? Highly disgusted by Safair and the crew. I have one more flight with Safair as I have already booked and paid for it but that will be the LAST time I EVER travel with them. I have requested for contact details for their complaints division and yet NO ONE has gotten back to me ? . I do have to say a very big thank you to Denise at Lanseria Airport (ticket sales ) for organizing another flight for myself and for finding my luggage - Denise your work doesn't go unseen so thank you !
