Missed a call

Robocall with woman's voice saying this is the final notice before the IRS sues us.  I can't tell you how many of these "final notice" calls we've received from how many different numbers they call from.

IRS impersonation scam: Just received a voicemail from a Private Number (unknown number) with a woman's auto voice saying this is a final notice from the IRS, who is filing a lawsuit against me. To get more information about the case, I should immediately call the 310 number. I reported the number to TIGTA (Treasury Inspector General for Tax Administration):

Getting many calls from several different numbers including this one threatening me. They claim to be IRS.

Same IRS scam as listed above. Call the number provided or risk a lawsuit from the IRS. Bring it on.
