NO idea who this is, but calls repeatedly every 20-25 minutes.

Called my fax#. Recorded message that they are conducting a "survey." What is my favorite team? Results to be announced at Saturday's SEC game.

I didn't respond. Likely it is a bot that is calling all possible numbers to harvest phones to call back for scams. I did call back the number and determined that it was not a working number.

Calls from this number continue to come in to our phone, sometimes multiple times per day.  I wonder how they're going to announce results at the half time of a game already completed.

Called it back from a burner. It says "disconnected or no longer in service". Spoofed number.

this is an UNKNOWN number that calls repeatedly.  Leaves no message, just annoying.  I am on the DO NOT Call registry.
