My mother received a call from this number, someone claiming to be from the IRS and threatening to have her arrested for unpaid taxes. Scared my dear sweet mother age 70+) to tears as she has always paid her taxes and been an upstanding member of the human race her entire life - I doubt she's ever had so much as a parking ticket. Fortunately she called me immediately and I was able to inform her of the scam. The IRS does not call you; they must send you a letter in the mail. I wish I could track these scammers down and have them drawn and quartered.
