Received a call from this number.  I don't have any contacts in San Francisco, so I didn't answer.  No voicemail was left.  I get a ton of unwanted scam phone calls even though I'm on the do not call list.

Caller said "hi this is Josh from customer service". I said "customer service of WHAT?" Then he said "oh good you can hear me. I wanted to let you know you won a cruise blah blah blah." I talked over him ( he wouldn't stop) and told him never to call me again and hung up. 3rd spam call in 15 minutes. Unbelievable.

Hello! This is Lisa from green light survey company! You've won a cruise!

Unwanted calls...no message.  Many calls, now also on cell #.

scared me, it is my sons area code..thought that something was wrong
