Red tape and poor customer service

First of all i called to momentum call centre for head scan authorisation and was helped by agent who almost finalised outhorisation and after her capturing information and me waiting on hold i was told that her collegue will finalise authorisation. I was put on hold again and when someoane finaly answered i was told that he will not finalise as it is logged as a new call. After giving information again i was told that no outhorisation number will be provided because my son is not registered under cronic conditions that allows us claim some costs and authorisation was refused. It is very unusual as other medical aids pay partial costs for this same procedure without being registered under cronic conditions and only request is doctors referal that I have . I requested cancelation forms and my family and I will be leaving momentum health after nearly 7 years and and not because I can not afford premiums or this specific procedure but because of momentum health red tape which is there to prevent customers from claiming. What else could be refused in future if i would choose to stay with momentum health.
