Called 7 times today all hangups, even when going to answering machine.

This # has called me several times no one there and hang ups!

Calls about 3 times a day for the past week!!!

This number kept calling me and I would never answer it.  Finally I answered it to tell them to quit calling and discovered it was a telemarketing company that in my case was working for a federation and they were calling members for donations.  Once I answered the call and spoke to someone, there has been no subsequent calls.
