Frustrated and at my wits end

Super frustrated with Discovery, and I don’t know what to do anymore. I was on the medical aid, then discovery cancelled it. They requested I reapply and submit medical forms and pay an outstanding balance, which I did on Wednesday 30/10/2019. I never heard anything and continuously have to call new business to find out what’s happening. I’ve called again now and told it’s been escalated with a 24 hour turnaround time. This is the second time now, and each time I have to be the one calling. Does Discovery not want my business???? The only reason I’m doing it with them is because my employer pays half. But if this is the way I’m going to be treated then I may as well join another medical aid and pay the full cost. Really now, it’s not like we paying a little money for insurance. It’s thousands and we treated like an irritation and I’m literally begging Discovery to accept my application... this is my last and final resort, as it appears customers get a faster turnaround time on this platform
