Worst hospital and no service or responses

My dad was admitted on Saturday 05th. At 3.30am I was called and informed he had a heart attack. I have tried countless times to reach the cardiologist (Dr. Lutchman) and hospital manager (Shannon) - 8 calls today and 5 x emails today and still no one has bothered to call me back or give me any information. Every day I have visited I have asked reception and nursing staff to get the manager or cardiologist to call me. I’ve called the cardiologist’s office (Dr. Lutchman) too and left messages, each time been assured he will call me, but days later and still no word whatsoever. And this is supposed to be one of the best hospitals? Pathetic and completely unacceptable.
