Received call from this number yesterday, didn't answer, they left an automated voicemail, saying that I'm being sued by the IRS, BOGUS BULL, the IRS doesn't make phone calls, they notify you by mail, usually by a certified/registered letter that you have to sign for, so they get confirmation that you received the letter.
It's the old IRS is filing a law suit against you call. It's a very bad recording that keep breaking up. The IRS does NOT call you. They send you a letter.
