I was sleeping and another part of the hospital at 1 o’clock in the afternoon and security came someone called and said that I was a vagrant I was grieving my daughter and I needed a quiet place what can I do about what security back to me

Security was only following up with the complaint , if they were unprofessional & wasn't understanding contact the hospital administration

I wouldn't blame security... They were just following up on a complaint. If you do still want to speak with someone, you could call the main number, ask for the security office, and request to speak to a manager.
