A breakthrough, perhaps? The day after informing PSE&G that I was escalating, I received this email:
Dave: Thank you for providing the service address for your request. I have found the DWMS job and we have issued the meter set order # xxxxxxxxxxx to our Inspection Department for review. I have sent an email to our Wiring Inspector for a status update. Thank you.
Maybe this is over. I hate to be a jerk about things, because I know they're busy as hell up there, but sometimes it's necessary to be the squeaky wheel.
