Calling Repeatedly!! WHO IS THIS!?

This is iRobot's customer service number.

http://pcefix.com/ Cold calling, fraudulently representing themselves as "Windows Technical Service" and claiming your computer uis calling them for help. They volunteer to sign in to your computer remotely and "Fix" whatever MAY be wrong. They also collect your demographics and sell them. Probably your passwords, keystrokes, and  internet history.
