I answered the phone on the first ring, said "hello" and only heard background noise.. then, I hear a guy say "Oh sh*t" and I repeated same back to him and hung up!
Got a call from 760-546-9382, and the Caller ID was "Escondido, CA" (in San Diego county). I didn't recognize the number, so I didn't answer. They didn't leave a message, so I blocked the number.
