Got a call from this number as well, just now. Didn't answer it, and they didn't leave a message. First time I've seen this number, but this is the second time in a week I've received a call on my cell phone from one of these numbers. I keep adding my name to the Do Not Call List but apparently that doesn't even make a difference.
I wasn't paying attention and aswered this automated call. It started out "Hi this is Sarah. I'm calling to talk with you about your IRS tax debt. President Obama ...."
At that point I hung up. Needless to say, I don't have any tax debt and I'm on the do not call list, which I realize these scammers do not honor.
