This is another number for the IRS scam whereby they threaten you. I was lucky enough to be told today that they will call me every day until I die because I am a fraud and another expletive, after I told them to stop calling my number because I know this is a fraud. They IRS will not call you and threaten you with a lawsuit without providing any specifics. Don't fall for it. This is the second time and the second number my husband and I have encountered.
