First of all, let me say I feel your pain.
We sent in our first K1 application last May (2006), and waited until nearly November before discovering that they had lost our application. Despite the fact that we have the receipt that it was received. My fiance finally got on the phone, and was able to speak to someone to confirm that it had been lost, and advised us as to our next course of action. So, with a special 'letter of permission' that said we could have two applications in process at once (just in case they found the first one), we resubmitted our entire application in December, have now dealt with and returned two RFE's, and are currently hoping for the NOA2 any day.
For what it's worth, with the second application we got a phone call that everything had been received and checked in, and then they lost my fiance's birth certificate. So he had to go and get a THIRD COPY of his birth certificate and send that up to VSC, as they said they could not process the case without that one critical document.
I would call sooner rather than later and see if you can get someone who can help you track things down - if only to know where you stand and what your next course of action needs to be.
Bureaucracy is a very frustrating thing

I filed the I-130 package on October 26th, 2007. It was received by VSC on October 29th. It has been almost 6 months, it is now 4-14-08 and no NOA1 received as of yet. No communicastions received period!
I called them several times but I am always told that my case is not in the system and that the EAC number that I have is valid but it doesn't bring anything up. How can this be? They cashed the check assigened a case number but are unable to find it? Frustrating.
I opened a case with USCIS on 2-27-2008 about a missing NOA1. Received an email on 4-10-2008 that stated: "Based upon the information you provided, the Vermont Service Center is not able to locate a record of your filing at this office." Fortunately I do have a copy of cashed check with a case number. I will be sending a copy of that to VSC on 4-14-08. I also decided to switch my process from K3 to IR-1/CR-1.
Could they really lose my case eventhough the check was cashed? Anyone had a simmilar experience?
