3 to 4 messages per day, I asked how to stop them, only would tell me I was hiding from the IRS. Call came from California, called back to California, asked where he was and was told the IRS is in Washington, DC, but then admitted he was in CA. Would not tell me what the issue was, but that I had not responded to two certified letters. I asked where the letters were sent, it was to my kids apartment but I have never lived there (though I am on the lease?) but they never received any letters. The man hung up on me, I called back and got the same guy but he gave me a different name and badge number, I asked for his supervisor, he refused to connect me. Told me I was threatening a government agent and he would add that to the charges. So I hung up. Good for a laugh. Tomorrow I will stop by the (real) IRS office and speak with them.
