Unsympathetic Dr from the Medi Clinic in Vereeniging

I have never experienced so much pain because of that Hospital. My Mom went in for a check up and was booked for a heart surgery by Francois Stemmert on the 31st of January 2022. We got a call around 1pm that our mother passed away while being operated, When we got to the hospital at around 2pm we were told he is in surgery with another patient. How does a man cause a fatality and then be in a surgery in less than 2 hours later? If they really care enough about their patients how did they allow that, or if he had any conscience in him whatsoever. So now we have a form that needs to be filled in by that man that caused us so much heart ache and he is just not helping us. We have been talking to his PA Karen and still we not getting through to him, they keep on telling us that He is busy with patients.
