No listing yet, call seemed local, and they called several weeks ago. Nothing on 800Notes or in Google, so called it.

Recorded message said "You have reached Won Energy. To be placed on the do-not-call list, press 1. To be connected to a receptionist, press 2."

Pressed 1 (since I already provided my number by calling them now) then blocked them with my local call blocker. Couldn't find anything in Google with "Won Energy" or different spellings. Saw there were other numbers starting with 952-300-xxxx that were scams, so this might be, too, or it could be an energy company trying to get me to invest.
