I am a total shmooze. I call and say things like "I know you're so busy, you guys are so great, I'm just so excited" and really lay it on then act like they are doing me a big favor (when in fact they are just doing their job) to make my appointments.
The squeeky wheel is the one that is oiled! So yes, call, be really nice, tell them how great they are, you know they're busy, but you're just so worried since that last letter expired, you want to make sure you're doing it right etc.
That is what I do anyway, but I am a natural shmooze, I know not everyone is. I have talked my way into and out of amazing things - my sister actually makes fun of me about it.
Good luck! At least something is happening!!
