If you cannot reach a person at the IRS to answer why you have not yet received your refund, call the National Taxpayer Advocate number (which I cannot put in here because the system will not allow me to do that but which you can Google). Tell them your problem and they will transfer you to an IRS person, although you may have to wait awhile on hold. It worked for me after waiting five months to find out why they were holding my refund.
