This is a scam. Recorded message, claiming to be from the IRS. Trust me, if the IRS wants to communicate with you, they write you a letter. They don't call, and they certainly don't send you a recorded message. THIS IS A SCAM.
Same as above, left message on answering machine claiming to be the IRS and that they are suing me. The IRS doesn't call, they send letters. Caller ID says wireless caller.
