Money to sponsor but no money for member!

As a member of Medihelp since 2007 and have not had to claim for any kind of serious injury. I was diagnosed with sleep apnea, I basically stop breathing while sleeping resulting in thickening of the blood, enlargement of the right heart chamber, inevitable danger of stroke and organ failure, high blood pressure, diabetes, depression and falling asleep while driving.I submitted the Neurologist's diagnosis and motivation for the use of a c-pap machine that monitors my breathing and forces oxygen into my lungs to prevent me from stopping to breathe.This machine costs about R16000 of which Medihelp only covers R7950 and I have to cover R8022 shortfall. I am not a person of considerable finances and are highly disappointed in this decision even after trying to explain the treatment to an uneducated consultant.Medihelp opts to spend my contribution on sponsorships for healthy living at the cost of my health by not authorizing full payment for preventative treatment, but would rather have me claim for the above inevitable health risks which will result in ICU or High Care for stroke, organ failure, blood thinning and blood pressure medication, insulin treatment for diabetes etc.
