Horrible service,useless medical aid

My daughter started started shaking and she is only 2,I called the pediatrician and she told us to come and consult ,when we got there she checked the baby and because lenmed Randfontein does not take classic Delta saver she referred us to another peadtrician at Flora for admission so that they can run the EEG tests overnight to find out what's happening with the baby. Fine we got to the Dr and he said admission, everything was done and they wanted the main member to sign when I called him they said no wait the authorisation has been put on hold pending investigations as there might be Pre existing conditions. Fine follow the process I will wait ,the lady based at Flora but works for discovery said she sent a form to my GP to complete and and he will send back that's where the investigation will start. I kept on calling my GP and he said no I have not received anything,I called they said they have resent,I called again they said we have resent,I called again today early they said they are calling the Dr to check and assist him if there is nothing still nothing and they promised to call me back I'm still waiting for the update. I called again later today to ask what's happening it's 15 days later and I'm not getting assistance,the lady who assisted me tried to check if they can send the forms to me but they said no. They are sending it again to the Dr but he is not receiving the forms. I am struggling with a child not knowing what the problem is and yet discovery is telling me about underlying conditions but they are not doing the right thing. Discovery is failing me and my child , discovery will pay for all this. 15 days later I and still being sent from pillar to post ,I am just emotionally drained,I don't know what to do or where to go. My last hope is the ombudsman,I need discovery to tell me what preexisting conditions they talking about. Such a useless medical,I regret joining discovery. You can die while they are busy focusing on wrong things. What must I do 😭 I'm tired of calling and holding waiting for someone to tell me unfortunately we have to send the forms to the Dr
