Someone from this number called my landline phone. They'd left a message that sounded very ominous, identifying themselves as "criminal investigation division," stating that there was "fraud and misconduct on my tax file which needs to be rectified immediately," leaving "federal badge ID #KB or KD 2849." The message sounded somewhat broken up or mechanical. I went online to find out whether the IRS ever calls taxpayers about their tax files. I found that they do not, unless they've first sent a letter.
They called my husbands work cell phone, which isn't published. Stating he owed back taxes and that they were going to arrest him. They provided 2 different case numbers, always put him on hold when they would provide a straight answer. We called the local athorities.
