Have you ever switched SA's at the same AD?

For a few reasons I've become less confident in my SA at one of my AD's in delivering on what she has said. Unreliable timelines, omission of info, pushing other brands now, etc. I'm self-aware and know that I'm no where near being a VIP client but her overall change in communication and backtracking has made me weary. I'm thinking of going with a different SA there. Has anyone done that? If so, did it become a better or worse experience?
