This number showed up on my caller ID day after day.  The caller ID said "Marietta Office."  They never left a message.  
So, finally today I answered.   Very pushy lady asked if I was Mr. Ray, and did I live at _____(my address).   I told her that we are on the "DO NOT CALL list."   Before I could say another word, she hung up.    

I hope these pests, whoever they are, will stop calling us!!!

Marietta Office is on ID.  I didn't answer.

all that shows on caller id is Marrietta Office

I didn't answer, they didn't leave message
