CID says California Energy. Called last night at 8:45 PM. I was in bed! I picked up phone but remained silent. Heard "boiler room phone bank" noise in background. Eventually they hung up. Another number to block!
12/30/16 14:08 PST Wasn't near phone when call came in, so let it ring through to voicemail. No message left and ID is less than informative. Will wait to see if they try to call again. If it does happen, they will be blocked.
This number seems to call every month asking if we need any repair services for our home. I told them I wasn't interested and to take our number off their list, but they continue to call. Unfortunately, the phone they are calling in on does not block calls.
