Being taken for a ride!!

After being denied a specific pump for COPD in early January - which my doctor prescribed, Fedhealth intervened, refused the pump and instead instructed me to go to a Pulmonary expert for tests to see the extent of my illness. Their instructions!!! I looked up and found a medical practictioner who is on their list of approved providers. After three (unnecessary) visits to my doctor on instruction from Fedhealth - to find me an alternative pump until the results came back - and after letters back and forth - today I receive the account from the Pulmonary doctor - over R1700.00 (oh, of which about R500 is not covered by Fedhealth!!!)..... Not even at the end of January, and for one complaint - ie my COPD - my husband and I are almost wiped out of savings for the rest of the year - and why? - because Fedhealth sent me on a wild goose chase at my expense. For this I pay R5000.00 a month. I want answers Fedhealth - as this is totally obscene and totally unacceptable.
