Received a call from this 415 735-3429. Phone rang, I picked up, said hello, no answer. Waited couple of second and a woman voice say, Mr.___?, I said, who's calling? The said Bay Area something And then blank pause, I repeated who's calling then the voice say call you hear me? I repeated for third time, Who's calling and then they hung up. Recently there's been scam call of recording people's voices by having you say "yes" and then unauthorized a purchased. People beware of this!
