My return is in the Error Resolution System for 12 weeks now UPDATE: Today is 115...ugh

I was told this by an IRS lackey over the phone. He mentioned 10 weeks but I'm going on week 12 now. 

 

1) How much longer will I have to wait?

2) What if they make a correction that I disagree with? Can I appeal?

3) Is there anything I can do to expedite my refund?
