This is absolutely the worst site I have ever seen...

This is absolutely the worst site I have ever seen!!! I have been trying since last night to sign in to the site to find out what my husband's PSA is. Of course, we are anxious to know. He has active cancer and it is scary each time he has his PSA done. The oncologist's office is taking hours to call me back. I still haven't heard from them. This site will not let me sign in. I hate it. I have called and the woman who answered blamed the problem on my computer. And, she was extremely RUDE!!! She thinks I am using an outdated foreign tablet or some other equipment. I am using a modern, nice, desktop computer. And, I do not have problems with any other site. If I am able to give my email address & password to Navigating Cancer, the next thing that comes up is a page that says that the page cannot be found or that they have an error on the site. Sometimes, the email address page will not even come up, so I can't do anything. This is extremely irritating!!!!! Please fix the problem.
