This is definitely a scam. Received automated call from this number saying it was Con Ed, and a technician was sent to disconnect service but couldn't gain access. The recording even stated my balance. I called Con Ed and the rep assured that this is a scam, and that there was no collection activity on my account, must less an attempt to disconnect. I was also informed that this number is not theirs. Con Ed would leave a number for you to call them directly if you were to receive an automated message from them.
