There are 2 phone numbers I can give you for the IRS. The one to check on your refund is 1-800-829-4477 and the general number is 1-800-829-1040. Or if you have a local office you can contact them to check on the status of your return.
Just add some additional information to SuperUser bluedeb's answer.
Call the IRS at 1-800-829-1040. Do not push for Refund it will send you to the automated check your refund, choose number 2, info about your tax account, listen to all options then select the one that says none of these are my topic, and you will get a live person.
OR: Try calling the IRS at 1-800-829-0582 x 362 to talk to a live person.
