Concerned for Future if Start is so Bad

I recently app**** for Bonitas Medical Aid. After submitting my application and receiving no response, I contacted Bonitas to find out what the progress is. Bonitas was unable to assist me and has no system to check new applications, and wanted me to reapply. I was concerned about a double debit order and therefore did not proceed. After a couple of weeks, I finally received a SMS stating that my application was successful. However, my Medical Aid only starts 5 months after I app****. I wanted to know why this is as I am concerned to have no cover for such a long period of time. I contacted Bonitas and I have received no response up to now. This concerns me, as most hospitals need authorisation from the medical aid before they admit you. If it takes Bonitas so long to reply to a general query, I shudder to think what will happen to me if I have to wait so many days for authorisation as well. Currently, I have no medical aid cover and I don't know why and I am not receiving any response. If this is the way Bonitas treats a new customer, it is clear to me that my business is not important to them and I will be looking around at other medical aids that will hopefully treat me better.
