Hi Sue - sorry this is happening to the business. Removing the shared fax number is a great first step. It will take a few weeks before we pick up the change in our clustering, so try to stick with it. Please don't delete the listing. That will likely cause more problems.
I'd like to get the separate business listing right, but which issue a redirect from bill & sue to bill? Perhaps you could use this common site as a landing page that gives users the option to select the desired site?
