Do consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.
Message left said - "Officially final notice from the IRS - notification that the IRS will be filing lawsuit against you - call 202-621-0445 for more information" This is most definitely NOT the IRS! Do not call the number back.
Number showed as Washington DC on caller ID.
