There is and yes it’s the normal number with a horrible phone tree where no one ever picks up.
I've seen a number of recent Supercharger installs where they don't put the phone number on the pedestals anymore.
Also I talked to a live human within 30 seconds the last time I called tech support (granted it was on a Friday night), and they actually were helpful in solving a problem I was having. Didn't have to do with a Supercharger however.
Maybe I've been living in the mirror universe or something, I dunno.
