This number calls me every afternoon between 4 and 6 pm. I never pick up and it never leaves a message. I googled it and found your website so leaving a post.
(415) 363-9713
San Francisco/North Bay Area -- this number called 3 hours apart a few times today but never left a message or I would decline the call. when calling back it never rings or goes thru. blocked them from my iPhone via the ios7 update. we'll see if they call from another number.
does anyone suspect Yelp? they're located in that area and all they have are automated phone systems... maybe a glitch in their system or some other company that any of us may have called before.
I got called 3-4 times a day. I blocked the number from calling my cellphone. I have a Samsung and did it from the call log. All cellphones can be programed to block the number. The missed calls show up in my call log, but my phone doesn't ring anymore :)
