Incorrect claim and poor customer service

I was admitted for a procedure in March. Authorisation had a scope that ended up nor being carried out. Dr has confirmed that it was nit done, yet the hospital still claimed for it. Since there was a copayment of R7000 plus, which I knew nothing about before the procedure, Med used my savings to pay a portion to the hospital. When I queried with Discovery Health, they referred me to the hospital. Case Manager Kajal confirmed and was not done and promised that updated information would be sent to the medical aid. This all happened in May. It is June now and the medical aid has just advised that they still have not received any updated document. I am.tired of being sent from pillar to post. Mind you I am the one that is busy calling.
