OP here--I did eventually hear back from here. . . 6 days later to confirm the appointment, where I will meet her for the first time (3 months after signing up with them). I think I will mention this concern to her directly, but at this point I also think I need to figure out who the supervisor is to let them know as well. It's CC, and yes, we've paid them.
Also, I don't want to do anything to put our match in jeopardy (meaning trying to switch companies or something). I am obviously optimistic about our incoming au pair (hence, why we picked her), but if we do need support, I'd really rather know we will have it. And I'm obviously hoping for the au pair that the LCC will facilitate a good group in the cluster, and this kind of things doesn't bode well there either.
