Bogus call saying calling from IRS

Received a recording on my answering machine stating this is the IRS..

They left a msg on my machine to call 206-734-4414 because the "IRS was filing a lawsuit" against me. This was my "official final notice". We called back just to mess with them but they never answered. Always a busy signal.

Same experience as other posts.  Threatening lawsuit and final notice from IRS. The obvious tip off was I called on Saturday morning at 10:00 and after 15 - 20 seconds got a live person.  Couple issues here: 1. Almost all government agencies are closed on the weekend. 2. According to news reports, it requires a wait time of at least 30 minutes, if your lucky, to speak to an IRS representative.

Same as other callers above, Saturday morning, IRS "filing lawsuit."
