Bombay Hospital — Door bell is not working in Neuro ICU Room

As i have observed today that the door bell of Neuro ICU Room is not working when i was visiting Neuro ICU room around 9:30 pm to give something to my mother that was asked by sister in-charge of my mother. And even after knocking the door for around 15 minutes no body came to open the door. After waiting for 15-20 minutes one of the sister came to open the door and told us that door bell(emergency and guest bell) are not working. And when i asked that sister where is the security guard. She told me that after 9 pm security guard is not available here and we are only the responsible person here to take care of whole ICU room. I found very strange and was shocked after listening this. Is this the process you follow here in hospital. What if, if there is some emergency and we want to talk with the patient. This is how you maintain and manage the ICU room facility. Door bell is not working, no security guard is available. What rubbish is this. I don't know what's wrong with Bombay Hospital service and management. I have stayed here for 3 days as of now and will have to stay for more 6-7 days. And i have experienced very bad management till now.
