CID says something about Grapevine, TX.  Left an automated message about "the IRS is about to sue you."  No reason why, no information at all.  I've nothing going on with the IRS, and I know very well that they wouldn't be making this kind of phone call until they'd sent lots of letters, etc.  So this has to be a scam.  Will refer to the Feds for further action.

I received 2 automated (SCAM) phone calls 1 minute apart on Wed. 7/8/2015 at 8:37 & 8:38 a.m. from the above # stating that IRS will file a lawsuit against me (my name was not used). I called the # back & all circuits were busy & I should try again later also automated. I will report this to the Federal Treasury at tigta.gov. I called the local IRS# & was advised to file a complaint online. I will do so & so should anyone else reading this message. PLEASE NOTE: IRS website states they DO NOT make phone calls before sending letters of notification. Thank-you & be careful always.......
