These clowns call every month or so. I have the same experience reported by others: the message says something about last chance to lower my credit costs; when you press 1 to talk to them, nothing happens; when you call the number back it is disconnected; reporting to the do not call seems to do nothing.
Live caller said she was with a breast cancer awareness organization and wanted to thank the community for its support during the last year. I asked to be removed from calling list. I'm on the National Do Not Call list. I have filed a complaint with www.donotcall.gov
