Yet another power outage

Just had a 20 minute power outage, for no apparent reason. And it came back on, with no apparent explanation. Calling the electric company demonstrated that there is now no way to get to speak to a real person, so all I got was that there was a crew on the way out – who never arrived. So I have no idea what that was about. Apparently it was only this building, as all our neighbors had power. This gets very tedious after a while.
