Simple task... not so simple for Discovery

I've been trying since the 14th of December 2020 (16 days now) just to change the debit order for my premiums to my new employer. Discovery only gets back to me every second day and with a different consultant attending to the query. I've submitted all required docs several times and every time "something is still outstanding". It's a simple task: 1. Completed form - check 2. Proof of ID - check 3. Approval / permission from employer - check 4. Some sort of employer registration - check

It's at point 4 that the difficulty comes in as my employer is a church. Not a NPO. Not a normal company, but proof was submitted. Just change the debit order.

If my family is not covered for January 2021, because Discovery can't perform a simple task, it's on them.
