How do I get the BRN to talk to me re: application?

I'm a Canadian applying for a California license. I sent my paperwork in January, and they replied quickly to say I was missing some documents (which I knew about, getting them was in progress, and by now they should have them.)

I had to re-submit fingerprints as the FBI rejected them the first time, but that was early March, and I have heard nothing since.

I've tried e-mailing the BRN to see if they've received everything, but they don't respond. I've tried calling, but just get cut off after listening to 5+ minutes of "go to the website" type messages, as "all our circuits are busy, try again later". I've tried calling at different times of day and never get through.

How do I find out if everything is ticking along with my application? It's been 5 months, by now should I have received the invite to write the NCLEX?

I realize they are busy, but I've been registered in several different provinces/territories and have never met a board as impermeable as this one! Is there anything I can do? After so many months I'm worried they don't have all my documents yet and I'm just on hold. I haven't written a snail-mail letter yet, is this the secret?

Thanks to anyone with any advice on how to get through to them!
