I got the same message y'all have. Funny though, I get a couple calls a day from the same area code saying "congratulations! You recently applied for a payday loan and have been approved..." and to go log on to some website with my info.
Received one of these and they left a message that I could barely make out, but yes, a serious sounding dude was telling me I am in big trouble and if I don't call him back, it will be seen as trying to avoid prosecution! Yeah, sure, buddy. Whatever.
Yes, I called him back and someone answered really to try to find out how much info they knew about me without divulging anything more than they already had. They really had nothing more than my name and address (which is scary enough by itself). He said they were coming to arrest me. Still waiting.....
Tax payer scammer. Recorded message. Don't call back -- total scam. IRS does not place these types of calls. IRS is require to do all official business via USPS mail.
