Got a call half an hour ago from this number. Caller ID said "San Francisco." I didn't answer. They didn't leave a message. The number is now on my blocked callers list. Thanks to others for your comments.
Got a call from 415-915-0747. As I frequently get calls from this area code for work, I answered but no one there. Just hung up. If this was a test call then I am likely in for several more spam calls as I, unfortunately, picked up.
got a call from this number (caller id listed the number) on my cell phone. did not recognize the number and don't know why they called a 619 area code - go figure
