Jen,
If I remeber correctly, I faxed my paperwork to the Rep. I would say fax to him/her, and leave a voice mail for them stating that you faxed it. If you do that, hopefullly they will call you back and leave a message, if you are not home, stating that they have it in the works.

I myself hate communicating by voice mail, but sometimes it is the only way, and can be effective if both parties participate.

Worth a shot,
