Citizenship

I mailed in the naturalization form in February. Got a Receipt date of 03/08/07. Fingerprinted mid-April with no problems in Alexandria, VA. I registered my email adress at their web site so if there is any movement I am supposed to get an email. VA cases are handled by the Vermont Process Center. So far no word and we are coming up on 9 months since the Receipt date. Any ideas? I called twice to the Cust Svc line. In October the phone rep. told me the VT office is working cases from DEC 22, 2006 still. When I called a month later another rep. told me they now are working cases from DEC 23, 2006. What is going on? Here I read about people filing and being a US citizen within 3, 4 or 5 months. Seems like the Vermont office is stuck. The timeline info posted on their site says they are working MAR 2007 cases as of OCT 15, 2007. How does this square with the info I received by phone? HELP!!!!!! Would making an INFOPASS appointment help? THX to all. Arthur
P.S. I have had my greencard since 1989.
