Yes, the caller ID said the caller's name is "NOT IN USE" ! I don't know what type of caller it is, they didn't leave a message. I am on state & national do not call lists, but that doesn't seem to matter anymore. I have even called the PA Attorney General's office about it. They just send out a form for you to fill out. I am so sick of getting so many of these type of calls everyday from so many different numbers.
