Who called from 2019150000

called my house phone mutiple times leaves no message then when I called the number back it says its disconnected.

Said they were from "PalmCo" calling on behalf of PSE&G.  Said they were going to be lowering my bill.  At first it sounding benign, but when they started asking for information from my bill I hung up.  Sounds scam-ish to me.

Says that there has been an area code change when trying to call the number back? But why would it tracr to a number with the wrong area code? Hmmmmm?????
