This number (360-284-4389) was left in a message on an answering machine saying to call "this department" immediately as "the IRS is filing a lawsuit against you." Obviously, this is NOT the IRS.
Recording supposedly from the IRS saying that the IRS has a lawsuit against me & I need to contact them at this number to discuss my case. A total scam!! The IRS does NOT contact anyone by phone, for one thing!
