left a message and said they are from IRS.

Called twice today, computerized message to call back same number as call i.d  shows. Funny just Google the number and it comes back with Brandywine Waterproofing. [***] Scammers hope you catch ebola

This number left a message saying my address was under investigation.
Will not call back as it is most likely a scam.

Same thing happens to me. They call and tell me they are with the IRS and my address is under investigation. I call back they keep hanging up on me or a guy answers and ask me to verify my name and social? I told them I wasn't confirming anything because I don't even know who they were. He told me they were team Anderson and he's with the IRS but then hung up on me . I called back they won't answer!

They keep calling and leaving messages about IRS investigation.  When I call back, a man who speaks limited English hangs up on me when I challenge his authority.  This is a scam!
