Kovai Medical Center And Hospital — Not Responding to OP patients

My Father was getting treatment under KMCH he was asked to come back after 15 days . When we reach out to them on the 16 th day they are not responding properly his tablets are over he has to take medicine we have to travel 4 hrs to reach the hospital when I called them they told we have to put an op appointment but for that I am trying to them from the morning they told only at 3 appointment will be take at 3 they didn't pick up the phone we kept on trying at 4.32 they took the phone and told op appointment is limited to 100 and it's done. How we should take it from here even I called the service station and she was lethargically answering the phone and directly redirected to another them .. this is how we are treated even when we pay for our treatment what's this hospital is upto..
