"Unfair cancellation of appointment"

Had appointment acknowledging letter and was told appointment date will be the next letter sent through the post. The best correspondence I received was one saying my appointment had been cancelled due to a Dr knowing nothing about me. No questions asked, not even an health form or check to explain my symptoms such as savere migraines, sharp pains in my head which cause my ears to ring which leaves me disorientated. Severe mood swings. Ive have my skull fractured in two places due to a violent relationship and and abusive childhood. But apparently this does not me me a prime candidate to see a neurologist. I'm so confused
