Frustrating service

To whom it may concern I am trying to join my new companies group medical scheme which is with Discovery Health. The service I have received thus far has been frustratingly poor. I short submitted some documents for the new application to which I have received emails requesting further documentation. Once I submitted the documents, the reply from Discovery was to forward a blank email with the same request for the documents that I had just submitted. I informed the department that i had just submitted those precise documents and requested further explanation. The response was to forward me the previous correspondence two more times with no explanation or greeting. I would appreciate a response from a representative that can explain what is further outstanding or required to complete this application.
