Diagnosis without a remedy

My Doctor referred me to get a sleep apnea test, It took two nights of being in hospital and a cost of R9500 for a diagnosis of having sleep apnea. I am now required to get a CPAP machine of which the cheapest is R10000.00. Bonitas now will not cover the cost of the CPAP as this cost must come out of your day to day benefits, A person needs to be on the highest plan in order for the full cost of a CPAP machine to be covered!!! SO Bonitas covers the test for diagnosis but does not pay for the CPAP to remedy the condition!! disgusting.
