MIOT Hospitals — About Nurse in Cardiac ICU

My father was admitted in Cardiac ICU. The Nurse working there treating very badly. any request you ask from them they show the displeasure and not showing any respect or help.
for ex: help like water or for going urine.

They always argue as if you should not come there again.

My father is 75+ now he is telling, he don't want to go there even in worst case.

MIOT Management, please instruct or give guideliness to the nurse how to treat the patients.
The Junior doctors who give the discharge details are talking to us are impatient.
