Recorded message saying they were from IRS (not the IRS, just IRS) & call was official final notice that IRS (again, not the IRS) was officially filing lawsuit against me. Instructed me to call office to get more information on file. Office number was same as incoming number.

Just received an automated call from this number saying IRS was going to file a lawsuit against me.  It's a total scam.  Don't people realize that the IRS doesn't call you.  They will send you a letter.

Received automated call twice today from number. Stating the IRS was filing a lawsuit and this was my final notice.  Little did they know they were calling an IRS number.  When called back the number did not ring thru.  Number to call matched number on caller id.
