I got a call from this number and I was obviously confused because I don't make enough money to even have to pay taxes. So I called back to tell them never call me again and this woman who has a really heavy accent said "hello this is the IRS how may I help you" and I said "uh yeah I want to have my number on the no call list because I know this isn't the IRS" and she said "can I have your first and last name and your zip code" to which I replied "can't you just block my number without that?" and she said "I'm sorry what's your first and last name" so I just hung up.
Recorded message on my voicemail saying that this is the I. R. S. to avoid lawsuit proceedings that I would need to call 323-861-9221 , than it repeated the number. Call that number it said the caller was not receiving calls etc. I had heard on the evening news about a scam calling claiming to be the I. R. S.
