Wow, I can't believe she treated you like that, especially with another client there, that's so unprofessional. I remember when I needed to switch to another CDC because my original one was too far away. She told me I was more than welcome to call her at any point, asked me to keep her up to date with how I'm doing and she even gave me the name of a CDC closer to me.
By the sounds of it that woman is horrible and you're well rid of her!!!
