"My child received no treatment"

My child spent nearly 8 hours in the Emergency Department waiting room seeking help. They have hepatitis and mental health problems. They were dangerously depressed and talked of suicide. I rang to find out what was happening when they had been there for 3 hours, and on hearing they were still in the waiting room, informed the nurse of their mental vulnerability and could they please see to my child ASAP.

After multiple calls, and being disconnected and hung up on without speaking to anyone, I finally got through to be told my child was still waiting but a nurse was in the waiting room with them.

I was called by the emergency room after the 8-hour ordeal and asked if my child was here. It seems my child had left without being seen. The only thing I can say is, in my opinion, this is gross negligence. I believe 8 hours is far too long to leave a vulnerable, sick person in the waiting area.

I now don't know where my child is or if they're even still alive. I believe this is totally unacceptable.
