I work for PG&E and this number calls 911 every 3 weeks or so. The police come as is standard policy and nothing can be traced to PG&E because is NOT a PG&E number! The number does NOT exist in the building(s) at 77 Beale OR 245 Market St. It has been investigated thoroughly and remains a mystery.
I have my desk phone calls go straight to my cellphone, and some of my outside calls (from people I know and whose phone numbers I know) come through to my cellphone showing this number...?!?
