My niece went in with a burning sensation in her throat and her airway was blocked

My niece went in with a burning sensation in her throat and her airway was blocked. They signed her in and told her to wait for the doctor. The doctor was a no show at some point I called and asked to speak to the security and the security said “let me cut you short I don’t want to waste your airtime we wont allow your niece to leave without the doctor attending to her and signing refusal form” I was asking them to let her go cause she is feeling better and will go to the doctor this morning but they literally held her hostage. The nurse also cut her off and said she must wait for the doctor. I asked my sister and neighbour to intervene they were met with the same nonchalant behaviour and refusal to let go of my niece yet she wasn’t being attended to. The doctor eventually came out and signed the refusal form for her now at 1:30am Abdul Gabriels is the name of the doctor. Guys I don’t understand how you can hold a person that isn’t admitted hostage while still not medical attending to them.
