No new documents resubmitted, but pushed back in line?

[meow85meow 3]

Hello. This is a half vent/half plea for suggestions, so bear with me a little. I had originally submitted all my documents in mid-October. Last week on December 4, I got a notice about my documents, and saw a message that one of my documents was incorrect. I went to the page they referred me to, but my documents were completely compliant to their request.  Confused about what I was supposed to resubmit (because the original doc was correct to begin with), I called NVC, waited an hour and a half on hold, and got connected to a person who (nicely enough) agreed that the doc looks fine and flagged it for her supervisor to review.  However, during this process, she mentioned in passing, "Oh, you resubmitted this document again today", which I DID NOT.  I think, somewhere along in the review process, I got pushed back in line with the same document, EVEN THOUGH I DIDN'T SUBMIT ANYTHING AGAIN.  I got connected to a supervisor who was sick with some type of cold and kept giving me vague answers about the document.  When I asked whether I should resubmit, she told me that wouldn't be necessary.  This has been about a week ago now, and still no change to my status. I now feel like I'm waiting in limbo just trying to figure out what happens from here. Does anyone have an idea of what my new timeline would be, or whether I should resubmit (it would literally be the same file) or anything?
