I would tell her straight up what you said here: that you dont feel comfortable with her receptionists and that they give you a hard time when you want to schedule out more than three appointments. Tell her how it makes you feel when you come in. She should absolutely have no qualms about addressing it.

I had a regular physician (dermatologist) that told me to ask for HER when I would call to schedule an appointment with an urgent situation if they didnt try to work me in (which has happened in the past).

It would be better if you could try to deal with them yourself first so its not just like you are going behind their back. Dont be afraid to speak up. Thats probably why they treat you that way... no one ever says anything.

She should be correcting them, or better yet, going up and scheduling your appointments herself to set them straight. She doesnt need computer knowledge to do that... she can just go up and stand behind them while they do it.
