This is not a "crank" call or someone with too much time on there hands. These are very malicious phishing scams, I would advise if you get these calls report it to your service provide and they will normally block the number from there network.
I was not home but a family member answered. A prerecorded message said you are being sued the IRS. Caller ID says "International 206-201-2799." Luckily, we all know the IRS sends certified letters not prerecorded messages. Wicked, evil people.
-SCAM- The IRS will never call you about a debt, so never respond to these kind of calls. All scammers rely on panic and the fear factor to intimidate you into an action that you will regret later. Tell them where to go and how to get there instead.
I just received a recorded message at 9:52am on 06/18/2015 saying they were from the IRS office and they have filed a suit against me for unpaid taxes and I needed to call 206-201-2799 immediately. I called and, like others who left comments, the person had a heavy accent. I couldn't understand what he said when he answered the phone but when asked if it was the IRS office, he said yes. After asking him to repeat himself over and over....what I got out of it was I owed almost $7,000 to the IRS resulting from an (alleged) audit they performed for years 2008 - 2013. I knew something was up when he said 78 cents because we all know the IRS doesn't use cents. However, when I asked him how much I owed per year (2008, 2009, 2010...) to total the number he gave, he couldn't answer that. He said the IRS sent me a certified letter on 02/20/2015, I didn't respond so they were suing me for the outstanding balance and asked if I wanted to go to court or did I want to "resolve it now." Wanting to see where this went, I said I wanted to resolve it now and he transferred me to an "IRS Officer." The "Officer" had a heavy accent too and when I asked him for the specific amounts per year that totaled the (alleged) amount owed, he hung up on me. I'm going to notify the IRS and our TV station here to hopefully stop others from being ripped off.
