We have a girl in our group who is not in our Service Unit (boundaries), she is from a completely different school district (suburb). But because no one contacted them for a troop she joined our group. Are there any girls in her class that are involved in a troop. You might email their mom to talk to the troop leader they are with. Call the council back and let them know you are not being responded to. And that you'd like to talk to the Service Unit Manager...they'll get you going.
OR you could always start your own troop...get some of the girls from your daughters class to join.
Wish I had something more for you.
