Dr Jeeva claims not processed

I contacted bankmed prior to scheduling sessions for my son with Dr Shabeer Jeeva to check if he is on the approved service provider list, they did not tell me that there were issues with the Dr. Now i have submitted a claim and was told that bankmed/discovery does not pay claims for Dr Jeeva, my first session was r3200 and 2nd session yesterday was r1700, that is allot of money only to be told that i cannot get my money back. Please explain what is the issue with Dr Jeeva and discovery as if i change to another doctor i have to start the consultations from scratch, and my son will be sent from pillar to post. Please can someone explain whats going on.
