Got a recorded message from "Caroline" at that number telling me to please call about the notification in my most recent JCP&L energy bill. The phrasing made me suspicion like it was folks knocking on the door asking to see your most recent energy bill from XYZ - which is not your power company. I was always concerned that they were looking for info they could use to switch our energy provider to the one they work for. Slamming I think the term was when this was done to mobile phones.
Anyway, I called Caroline back and immediately got a "please stand by for the next available account representative" message that was slightly speeded up, then a speeded up version of The Minute Waltz, then "The user at extension 8...0...0... is not available. Please leave a brief message." Then, "This mailbox can not accept any more messages." *click*
This was the message, Hi this is Carolyn from JCPLU utilities calling about your recent notice with a recent statement on your bill. 848-204-1382. Scammers! I'm blocking the numbers. Don't respond to these scumbags!
