Just reapply if they can't find you in the system.
I had my sis apply online...and she never got a response, after about a week. We tried the access number lookup and....nothing.
Called: they couldn't find her in the system. So, right there on the phone, she applied "again" and was approved, got her access # and her packet came shortly in the mail.
Just reapply: you'll get it. If they can't find you...it was just a glitch in the matrix.
"...what good do your words do if they can't understand you??...."
