I too am on the don't call list. can't under stand why they would call me, as i don't owe any back taxes. phone reads" tax 130558721445".on my caller ID.
I have received a call on my cell for over 6 days from this number. They leave messages that they are the IRS. Same as the above comments. I am calling the FCC on this as well. i HAVE NO debt with them.
