Oh Jeez, that's horrible, I am so sorry, I would suggest you keep calling USCIS and insist they look at your file. From the site that I have there is 24 Cases still pending for review. By this month they should have started to review your case. Good luck, patience is the key to all this, the next steps after being approved or not becomes another huge hurtle to overcome, but at the end it will be worth it.
