Squeezing money from patients although full authorisation

Not a good experience. I suspect they working with med aids to make patients pay portions of the bill. Authorisation for the procedure but still I have to pay over R3000 in. Gems ignoring and gaslighting and Netcare squeezing me for payment. No sympathy for the patient. I think they did not do enough to get outstanding amount from. Gems. Very disappointing. Consumers getting poorer. Be careful consumers.
