try waiting for another week or so, it might take even more. my number was available after 3 weeks.
two ways to get it...either after 3 or 4 weeks call them up and ask what your number is like I did.
or you can just wait for the mailing they send out to you after a couple of weeks, i think mine took about 5 weeks or something like that, i really cannot remember.
