The only way I have any success is go through Bonnie. She will forward your e-mail to respective department/individual. However, even doing that does not mean you will receive a response. I have one e-mail out still waiting for a response.
When I was able to get through, the response was it is an IT problem and they were looking into it (that was four months ago), so it sounds as if the IT deparment is still working on it.
