Some pdocs are terrible!

I tried getting a pdoc at the local mental health center. Here's how it went:
Create an appointment for end of July
Late July he calls and reschedules for late August
Second week of August he calls and reschedules for early september
He calls again and reschedules for late september first thing in the morning appt
Late September I go and wait over an hour. I ended up leaving without seeing him.
And some how on my records he diagnoses me with schizophrenia??? Without even seeing me???

Also prior to this when I was still in adolescent services I had a doctor who put me on Seroquel. Well after a few months I overdose on seroquel and the hospital takes me off it. He was pissed to findout the hospital took me off seroquel and asked me why they did that. Ummm, I tried to kill myself??? It wasn't working???
He refused to give me a prescription for the new med I was on and put me back on seroquel. I was back in the hospital within 3 months.
