Spoofed number. Callback says nonworking number

Not true, callback said press 1 to be added to their no call list.

Shill much?  Why in the world would you press 1 to added to a no call call list from someone who calls out of the blue?  The FTC advises people to not do that.  You are only encouraging more calls.

You signed up for the Do Not Call Registry ages ago, but you’re suddenly getting a bunch of unwanted calls. What can you do?

Hang up. When you get illegal sales calls or robocalls, don’t interact in any way. Don’t press buttons to be taken off the call list or to talk to a live person. That just leads to more calls. Instead, hang up and file a complaint at donotcall.gov.

The # came up this early morning. Did not leave a message.
