This same message was left on my machine too. Sounded like a little kid.
I have a mortgage with WF but not late. There was also a phone call a couple hours earlier on my machine, where I did not pick up but could hear, with someone that waited about 3 seconds and then hung up. My caller ID DID NOT even register that someone called!! I have never had this happen where a call was completely NON EXISTENT.
Strange indeed. It may or may not be WF. It could be someone using them.
Keep posting experiences, let's get to the bottom of it.
