"Left alone and frightened"

Have been getting dentist treatment and adult services within community and hospital and getting emergency support over a prolonged time and been sent from one place to another. Not having the correct support and put in a room with 2 sofas and left alone and frightened and told treatment can be whenever? Poor service for people with neurodivergence. Young man in severe pain told to go A&E for emergency treatment and then told to wait in a room and sat waiting in severe sensory pain and told to wait for over an hour and no one would listen.
