Got a recorded robot voice on the voice mail, called back and a man answered saying he from the IRS. asked for our name, When I asked to speak with the lady that left the message he hung up on me. My wife called him a few minutes later. she asked for his name and he said "mar, oh no that's not my name, it's Coleman Agnes." she asked for badge number and he said he didn't know what badge number she was looking for, then he changed his voice and started hitting on my wife. I got on the phone and he was acting drunk and all of a sudden had no idea why i was calling him.
