Difficulty to simply add a dependent

I phoned Discovery about a month ago to add a dependent to my Life Insurance with Vitality Integrated. After my first phone call, I was phoned back barely 5 minutes later because they forgot to ask me some details. I received a bunch of Medical forms thereafter to submit, which I did. A few days after that I received another bunch of Short Survey Forms that I need to fill in together with screening test results. Nobody phoned me to schedule a nurse, so the next logical step was to do a screening of the dependent at one of the Discovery Wellness Centers in Centurion. The results were submitted digitally from the center and via email, after which I followed up with a phone call, where they told me it would take 72 hours for processing. I waited and we only got an email they are awaiting medical examinations. That was the detail. We phoned again, and Discovery resubmitted my email with the details, also saying that Discovery might not accept the results since it was not done by a sent out nurse, which they never sent. They said we should wait 72 hours again, so now it has passed and we are still waiting. The screening cost us R350, and telling us that Discovery might not accept the results from one of your own Discovery Wellness centers is really contradicting.
