Best med authorization

I have been admitted in trauma unit the whole of Monday, I had to leave the hospital as I cannot to pay cash. We take medical aid to cover us in a time of need. I am new with best med and in July 2025 will be a year, since Tuesday they have being reviewing my case and have never provided any feedback unless I have called in. I have severe pains in my back. I have sent in all required documents to best med as requested, although I was suffering I tried the best from my side to fasten the process. The hospital is wanting to admit me and best med held a meeting on Thursday at 1pm (13/02/25) to discuss cases like this. Today is Friday 4pm and I have called in numerous of times for feedback, all I was told is that feedback will be emailed to me before 4pm, best med and had **** about providing feedback. They are also wanting to cancel my membership as to none disclosure, there is no reason or answers provided, thier offices close at 4pm. How do we manage with service like this? Made a mistake taking cover with them. They have no urgency when it comes to service.
