I do not answer unknown numbers, hence, the call goes into voicemail. This is the transcription: "I've been trying to reach you. This call is officially a final notice from IRS Internal Revenue Services. The reason of this call is to inform you that IRS is filing lawsuit against you. To get more information about this case file please call immediately on our department number 972-698-4561 repeat 972-698-4561. Thank you."
I've received this before and it's spam.
