Very interesting that other people here say that this number is trolling in Pennsylvania re electric service. I am in Minnesota. And we have no "alternate" electric service providers here. The robot's computer must have gone wacko.
If it's a bogus call, just create a DNA (do not answer) SCAM person account in your smartphone address book and add all these numbers as they come in to you. Don't forget to give the person a very special, stupid ringtone so you you won't accidentally answer.
After a while, you can rest assured that the marketers stuck in the old ways are in control!
