This appears to be a tax scam. The voice mail message was a recording claiming to be the IRS, a final warning that they were going to sue me. I reported it to the TIGTA at their “IRS Impersonation Scam Reporting” web page or call 800-366-4484.

Thank you for providing farther information. I also reported them.

just received a call from 202-368-4717 about  an IRS Law suit against me. Scam big time. They wanted a credit card  number. Said I was being sued by the IRS for $2985.00 for tax evasion.
