Didn't answer but automated message left that if I didn't call them back, further legal action against my name would take place. Deleted message. With nothing outstanding, just guessing is a fishing expedition.

Somebody called me from this number and left a message that further legal action against my name would take place. When I called back he told me that he is from IRS. When I asked few questions he hung up

Same thing on my end. Called them back and started to ask questions and he hung up

240-547-2515 called my house and asked for my by name.  They told my husband they were the IRS and needed to speak with me immediately.  I skeptically called when I got home, I was told I reached the IRS.  I think they heard the doubt in my voice, because I do not believe the IRS would contact me over the phone, and said "Scott is my case worker and will call me back."

Got same call - message
2515. The issue is very time sensitive. So before I take any legal action against your name. Call ARS as soon as possible."
