Just got a call from this number with no name on caller ID. The recorded message claimed the IRS was now going to file a lawsuit against an unnamed party. This is obviously a scam since the IRS doesn't call never mind robo call. They'll send letters. Not to mention they wouldn't have to sue to get the money they claim is owed them. It would seem that these folks are stepping up their game since we've ignored the threats that they're going to send "the local cop to arrest" someone.
