Robo call, returned call and spoke with a Dan Stewart who said his ID number was 25173. He got all offensive when I started to question him and ask him about employment and what district he was working out of, he said I could google his name and I would find out his information but of course there are thousands of Dan Stewarts in the world. When I confront him about my information he told me I was NOT under investigation. He said we don not make robo calls, I informed him that I called the exact number that came up on my caller ID and the number that was given to call. He told me someone was fraudulently using that number, so I told him as a supposed IRS agent that he should investigate this phone scam. He said that wasn't his job and hung up.
