Caller type: Unknown
They call me all the time and never leave a message. I never answer. I think it is a scammer spoofing Duquesne LIght's actual phone number on my caller ID. I still have a 412 number but moved out of Pittsburgh a long time ago and I have not been a Duquesne Light customer in about 10 years, they have no reason to call me.
