Bad service from Discovery health

So I belong to Discovery health a couple of years ago I had medical aid through the company I worked for . I login and passwords was linked to my work email at the time .... so I recently joined Discovery again I have phoned multiple times asking them to update my information because I don't have access to the app because all my information is linked to my old email address .... so what ****ed me off a few minutes ago is that one of your consultant dropped the call while she was busy with me .... so can someone please phone me to update my information so that I can access your app ....
