Who called from 6507310705

I just got a message from this number saying Hey Kaili! Jeremy added me to a local circle... Who the f*** is Jeremy?!?! and how the F*** do you know my name...

Got a text:

Hey L**** (my name), Rory sent you a message and added you to their local network on Circle.  Install to view.http://circleapp.com/downloa?sms=2

How do they know my name?
I don't have a friend named Rory.

Change your password to what?

I have a corporate Facebook account. At work I go by a different name and it is on my corporate Facebook. When I got a text from this number it called me by my work nickname. They get your number from Facebook.

I got the same request to join the "circle app.com".  The twist is they somehow know my wife's name and addressed the text to her.
