I consider these calls harassment and stalking. I will be writing my US Senator and Congressman to bring this issue (and this particular number as an example) to their attention and ask that they expand the "do not call" program to include non-profit organizations. We get 6 - 10 calls a day from solicitors --some people, some computers.
Caller asked for my wife by her first name. I told them she was not here but I could take a message. The man stated he was just calling on behalf of firefighters and wanted to remind us to check our firealarm batteries?!
They call almost everyday. Never leave a message. When I called the number back from my home phone got "system busy" signal (not "line busy"). When I called from my Verizon cell phone got message from Verizon that the number is disconnected or no longer in service.
