guess no one answered you on our boards... sorry! the time i've seen from everyone who's gotten thru has been between 2 and 6 weeks... we took two weeks, and that seems to be the norm, but it's not unheard of for them to take longer...
i think if you miss the first call (or they couldn't get thru for whatever reason), it can take them a month to call back....
also, with the current state of affairs, things are undoubtely backlogged... even if the office was open, there is no guarentee all staff showed up for work last week... i'm not sure i would have left my house if it was me....
try writing them an email and inquiring... sometimes people get results this way...
good luck...
