Chaos - It could be that they don't want to start care and then you are going to leave OR they provide a care that the UCSF doctor will not keep you on. It also could be they don't feel as competent as the drs at UCSF. There could be other reasons as well but those were my first thoughts. Where I live, switching neuros is difficult because none of the neuros wants to "steal" patients from another one. I experienced that when I switched. I did explain to my new neuro the reason for switching and he was on board with it and understood my reason for switching.

You can always be put on a cancellation list and may get in sooner. I did that with my rheumatologist and got in within a week as opposed to 2 months. I hope that they can help you at UCSF and that when you appointment finally gets here, things will go well for you.
