Terrible communication, no one responds to queries

I have been with Bonitas for years but their lack of professionalism and terrible service is really exhausting me. I could go on forever about how they refuse to pay for things, but I have decided to stay with them for convenience at this point. My boyfriend wanted to join as a dependent. I filled in the forms and have emailed Bonitas THREE times to figure this out as he needs to be on medical aid soon and at this point he isn't sure if he wants to even use Bonitas. Maybe there's a reason people join Discovery and other medical aids. I even queried through their Membership portal and NOTHING.
