Nothing to worry about; they are that busy. I got that same message last time I called there (last week Tuesday) and didn't get a return call until Wednesday afternoon. With all of the news that has come out lately, it isn't surprising. I know they had thousands of emails on signing the commitment alone. They haven't and they aren't going anywhere. Just be patient, and persistent; but never rude or yell. Just for the sake of trying, call the regular number and see what you get.
