This number called our house yesterday.  The caller, a Miss Roussel (didn't catch the first name), asked for me by name (first and last).  She claimed to be with General Electric Security, kept saying it wasn't a sales call, and offered to have an agent come by to put a sign in our front yard.  Umm... no.  I told her we already have a security system; she asked how old it was.  She was quite persistent, unprofessional, and rude.  The number came up as "Unknown Name" on our called ID.
