Gap cover cancelled with contact from Discovery

So on the 1st of May we changed the main member on our medical aid from my wife to myself. Out of the blue our GAP Cover policy was cancelld without so much as a phonecall from Discovery. Since then we have been trying to get the GAP Cover reinstated with no success. I have completed all the required documents and we made a manual payment for the May premium as requested and still no success. Last Friday it finally looked like something was happening, but now the main member has been changed back to my wife and I have no idea if the GAP cover has been reinstated. Nobody has come back to me and when I phone I can get some information, but nobody can tell me what still needs to be done and when it will be done. This has been extremely bad service from the managers and call centre agents. I don't understand why this is so difficult to reinstate an existing policy just with a new main member and after doing everything they ask it still has not been corrected a month and a half later.
