Received multiple missed calls from this number today. Error message comes on when I try to call the number back.

same here

Got called by this number multiple times as well and when I try to call the same number back, it says that the phone number is not in service...

Got called more than 5 times by this number, chose to pick up after that, found out it's a survey about SF elections. I entertained it for a little bit, but realized soon after that the caller is 1) not from SF, 2) has no idea what the hell he's asking me about.

Received 3 calls from this number yesterday. Have received multiple daily calls over the past 2 weeks all without a msg. Caller ID reads SNFC CNTRL CA. On callback phone number is reportedly not in service.
