Are you still getting paid for the work you do?  If you're still getting paid for the work you do... well, contractual instability happens, and the issue is being handled at levels above you.  The uncertainty is unpleasant, but there's not a lot you can do about it.  For now, just keep working and keep getting paid.

At the same time, if I'm reading this right, it's not a particularly good sign as far as long-term stability of your position, and you're not getting paid as much as you should be.  That means that you should be sharpening up your resume and looking for another position.  It's *possible* that your current workplace will give you another contract at some point, but by no means guaranteed.
