Manipal Hospital — Dialysis

I get my father for dialysis thrice a week to Manipal hospital goa. The dialysis staff is high unprofessional. Especially the department head supervisor Mr Sunny, who is arrogant and unprofessional. He refuses to give dialysis treatment to my father if I question about his dialysis machine which are not working and defective. He threatens us saying that we cannot do anything to them if anything happens to my father during dialysis as we have signed a consent form. He is very arrogant and rude in his approach
