I assume you know the checkee's website? Here is the link: www.checkee.info. You can check how other cases are going. Keep contacting the Consulate/Embassy. They may not respond, but there is not hurt to give it a try. I got their replies (not automatic replies!) couple times, though they were very inefficient at certain point. Again, contact the international student office at your school. It is part of their job to help you out under this situation!!
I hope it can help you somehow. At this point, keep your spirit up. Don't let the procedure ruin your life!!
