In hospital procedure, wont pay!

I unfortunately landed up at Bonitas after Liberty Medical Scheme closed and all contracts were transferred across. It's been a horrible experience / relationship from the get go. My latest bump in the road revolves around a dental procedure which cannot be performed in the chair. This has been acknowledged by 'Denis', their dental division. Unfortunately, Bonitas subtly removed certain procedures from their dental plans, so they will not pay for ANY dental procedures under anesthetic, even though they acknowledge it cannot be done in the chair. They now recommend I apply for ex gratia funding. For this they want: 1. Full income and expenditure (me and spouse), 2. three months bank statements 3. Our latest IT34 tax assessments 4. proof of income and 5. A motivation from the surgeon (WHICH THEY ALREADY HAVE!). It's quite simple to me. This is an in hospital procedure, which should be covered!! If you are looking at a medical aid, stay away from Bonitas. Have a look at how many 1 star reviews they have. You have been warned!
