shivapva,
If I were you, just go ahead and schedule the appointment.
You have nothing to lose, beside they may schedule you 2 or 3 weeks from now.
In my case, I efile on 12/6 and was schedule on 12/30. I was told I need confirmation number when I show up. But, when I arrival at district office @ Jacksonville, I showed the security guy the PDF receipt he lets me in and did not asking me any question.
I even feel call 800 scheduling is waste of my time.
I should have drop by Jacksonville office earlier w/o appointment, I believe they will take my finger print and photo as well.
If your district is local, give it a try just driving there, again, you have nothing to lose.
