This annoying number called me twice in a row, one ring each time. Made the mistake to answer, I said "Hello" and a female voice said "Goodbye" and hanged up! It better not be hackers! Do not answer their calls!
I receive calls from (415) 287-6010 multiple times daily. I do not answer, but was curious & so I called the numbber back. This is part of what I heard: "...this phone# has been disconnected or is no longer in service..." I believe this # is of San Francisco, CA origins.
