Discovery & their Poor treatment, but very expensive medical aid

When it comes to payment, Discovery seems be all over the show but when it comes to claims and assistance from a very expensive medical aid they seem to be full of every excuse they can come up with. My Father whom is 75 years old went for his 4th back operation. They fused his spine from S1 up to L5 that is 6 segments that has been fused and this makes is a level three operation. Well that is what we thought, then it came time for my Father to receive rehab as this is whole new life style and there are things that he should not be doing anymore. The declined City Med as they needed more segments to be fused and according to Discovery this operation was only a level two, even with the bone sc**** they did from the hip bone to add to the spine, this still did not convince Discovery that this needed the best after care. I have never been this disappointed, they way Discovery treats their elder is leaving me without words. Do you know what it is like to have the 4th back operation and this one at the age of 75? Dear Discovery, may I never cross paths with you again.
