They have a recorded message that states, " you are being sued by the IRS" please call this number back for critical information. Sounds like a scam to me!
I called back from a different number than the one they called me on. I said that I had received a bogus call and voicemail from this number. The guy said he was going to transfer me to "an agent". He put me on hold for 3 seconds and then picked the phone back up and said "you've been transferred to an agent, how can I help you". When I told him I knew he was the same person, he just denied it. I hung up. I definitely think it's a scam.
