PMB claims. Lack of information

It is extremely difficult trying to get information from you regarding a PMB claim. I am not prepared to spend time getting accounts from service providers who don't send them to the patient, but straight to Discovery (which is the first problem) nor get my doctor to fill in forms for which I have to pay for - and then be told by Discovery that these things are not even claimable. There must be someone in Discovery who can actually answer queries on PMB's (not chronic) without expecting the patient to first go the above route. My issue is quite simple. It is regarding cost of tests to confirm you have a PMB and level of cover for the treatment the month after leaving hospital.
