5071C - Verify Identity not working!

Hi, On March 23, I received IRS letter 5071C asking me to verify my identity before receiving my refund.  I went to the website and entered in all of my information accurately and received an error message that the information provided is not accurate.  I verified it FOUR times - and it still would not take our information.  The phone # is down - they are not taking calls!  I tried again on the website - www.idverify.irs.gov and now I am getting an error message that states my email address is invalid! WTF  I entered 3 different ones and it wouldn't take any of them!

We have a large refund coming and need this money and I have no way to verify our identity to get this refund processed!

Any ideas how I can get in touch w/ the IRS to complete this process???

Thank you!
