When you called/emailed them, did they tell you whether they finally got your materials or not? If not, I would either contact them again, or if you think that wouldn't serve any purpose, I would email/fax/fedex the paperwork in question.
From previous communication I exchanged with them, I got they have a lot on their plate right now. Last year Annenberg alone got 250 PhD applications, that's a lot of stuff to process.
