I got 3 calls in an hour 2 were 11 minutes apart. I called it back and it is a political organization that says it is exempt from the do not call list. They did give me an option to select to get off their call list. We will see how that goes.
Same thing, called it back and said it was political but they were exempt from do not call list - press "1" and they will not call back. This has worked for me with several political/marketing numbers if you call them back.
