R1000 More for Discovery Health Overnight!

Discovery just increased my medical aid contribution from R1 459 to R2 454 - that's nearly R1000 extra! Close to a 70% increase overnight. what the heck! And on top of that they inform me about this R1000 increase 5 days before they're about to make the debit order. And when you try call them to dispute the matter you simply can't get through to anyone. Terrible service!
