Pathetic staff etiquette

This is the worse hospital I have had the displeasure of being stuck in. Because this hospital is a heart hospital I was brought here. The doctors are great however the nursing staff in the ICU unites offer pathetic service. I will not recommend this hospital to anyone the nurses have conferences about patients and laugh when you complain as they feel they are untouchable . The unit manager has ignored me for 7hours without assistance simply b cause she feels she is entitled. She is now enacting a personal vendetta as I screamed when I was in distress now she wants to make me suffer as there are no recordings in ICU
