Also received a call from 435-625-1075.  Being sued by the IRS and that we need to call immediately.  The IRS sends letters notifying you that you owe money and if you don't respond they come certified.  This is the second time we have received calls like this the first time I called and a guy answered immediately, wanted me to pay over 10,000.00 to stop the law suit.  Funny thing is if you anyone has ever called the IRS you sit and wait up to 30 minutes for someone to answer and they always give you their ID number and first name.
