Discovery Health website and call centre = horribly disappointing

I need to remove my daughter as a dependent on my Discovery medical aid plan, by the end of November, as she will be on her own Discovery medical aid plan from 1 January 2021. My specific gripe is that the Discovery website consistently (over the last week, as I have been - repeatedly - attempting to remove this dependent) provides an error response (due to a "technical error"), and the Discovery app likewise, in additional to referring me to call a consultant. The bot and WhatsApp lines are equally unhelpful. On three occasions my telephone call has been cut off, after 8, 3 and 10 minutes of holding (i.e. not even getting through to a consultant). The "excellent service" referred to by Discovery is an indictment on them.
