If you received a phishing warning but believe that this is
actually a legitimate page, please complete the form below
to report the error to Google. Information about your
report will be maintained in accordance with Google's
privacy policy.
Unfortunately we have done all that. It is not a domain issue or safe browsing issue. The best analogy here is let us say lot of customers run a default drupal or joomla site under their domain and Google chrome show these sites as phishing site.
Please host the HTML source of a page that throws a warning somewhere. And mention the version of Chrome that gave the warning ( chrome://chrome/ ). Also can you post the thread on the Google forums with a proper bug report? I can't find it.
Use Google Webmaster Tools for your product site and check for issues: https://www.google.com/webmasters/tools/home?hl=en
Try to come up with a reason why this may not be a false positive. Perhaps you have trademark issues? etc.
