Left a recording saying that the IRS is filing a lawsuit against me. My CPA said it's a scam. I never called the number back... But it was scary at first however I trust my CPA and he said the IRS will never call you... They would send you cerified mail.
Report this number to your local Attorney Generals Office by going to your State Site and filling out the form: They will take it from there. I got one today too saying they are the IRS and have a suite against me! The IRS will not call you, they will just show up at your door. Do not answer the call nor call them back.
