Why are you panicking? Its just been 2 months. Yes USCIS may have messed up the work order but its too early to take any action on this. As I have mentioned earlier somewhere, its useless even to put a case inquiry right now. Once it crosses the 3 month mark then maybe you can start to voice this. But I don't see any other way right now than to just wait.

I understand your case and that you can't start your job without the EAD, but it is what it is, even if you voice it, it will still take months. With past experience, placing a case inquiry only causes more delay. Have patience, wait it out.
