Received a call on landline.

Caller left a message that the situation was critical and that if I didn't return the call immediately all they could do was sit back and watch the situation unfold.  Vaguely threatening

Keep getting calls leaving robo message "Attorney of records to return the call. The issue at hand is extremely time sensitive. My phone number is 253-216-0655. Do not disregard this message and do return the call. Now if you don't return the call and I don't hear from your attorney either then the only thing I can do is wish you a good luck as the situation totally unfolds on you. Goodbye."

Same message as the other people above.

This is the second call I've received, except from a different #.  The original call was so pushy and threatening that I had a horrific anxiety episode and was sick for days!!  Same message both calls as above recipients!  This time when I return the call, they answer "IRS, what is your case number?" When I told them I wasn't given a #, they wanted my name--I told him if he called me and I'm in trouble, then he should know my name.  Besides, if the IRS has a problem, they don't call on the phone!!  I asked his name and he became verbally threatening and I hung up, as my anxiety was setting in again... I was not even working at the alleged time of the so-called "fraud" that I allegedly had perpetrated!  They are the frauds--how does the phone co. Let this kind of thing go on??
