Caller ID says "South San Francisco Bay Area" - a dead giveaway that the caller is not a resident thereof. The caller did not leave a message. I, too, find the 118 prefix to be strange. I assume the caller is a spammer and have blocked the number.
I get a call from this number about once a week or so. Today I actually answered, usually I let it go to VMX if I don't recognize the number. So I said hello, somebody said, Mrs. (my last name)? I said yes, and they hang up. I mean seriously WTF? They have never left a message either. I don't have time to report every one of these [***] so I have quit answering my phone pretty much.
They try to get u to say "yes" so they can record it and sell their product to u by dubbing "yes" into their sales pitch. Then they send stuff w your approval....
NEVER SAY YES! Ask "Who's calling" instead... Or just don't answer!
