I've gotten 5 or 6 calls from these idiots

this number calls all day everyday with no one there and no message, nor can you call them back at this number.

Update on original post:  it's the National Republican Senate Committee soliciting - fianlly got a human to answer.  they were very polite when asked to be removed from their calling list, which takes 48-72 hours to take effect.

Call me daily, often  and leave no message!

Same experience.  They call, I answer they say nothing.  They never leave message  They call twice a day for over a week no weekends tho'.
