Aged Claim, many email acknowledgements, no action

Good day. I act on behalf of my daughter (as duly authorised by your internal process) who is a relatively new Medical Aid member of Discovery Health. An account for a medical aid consultation by Dr LR Graves dated 19/09/2014 was dropped in your Claim Box at Vincent Pallotti hospital in Sep 2014 to which no acknowledgement was received. Since then numerous claim copies have been emailed to claims@discovery and health@discovery with the usual auto email acknowledgement of which the last reference was *** (I can quote at least 10 or more of these references). Calls have been made and correspondence entered into, however NOBODY IN DISCOVERY HEALTH can finalise this matter.
