Claims they are the IRS seeking legal action against me. Clearly is a robot automated message.

Received the same call, robot call saying they calling about an IRS legal action.

I got this same call about the IRS. Though the number they asked me to call back is the same one they called from. I'm wondering if they're worth pestering/wasting the time of like those false tech support calls.

Revs fake call

Received automated message claiming "huge legal problems for me" if I don't return call. This is same type of scam call I've received before - just a different telephone number.
