Robo callers.
Hung up when I answered, but a call back is a recording that says "To be placed on a do not call list for the number that called, please press ONE now..... *pause - and note, I did NOT press a button!!)*
We are sorry for the inconvenience. Please allow us 48 hours to remove your number"

So this is a crock of crap. It's a simple recording that just assumes you will press one.

Hit 1 when the recording starts, and tell the live person who answers where to go.

Complaints filed with federal agencies this morning and caller under investigation.

Called, no answer and then asked to push 1 to be removed.
