Dreadful and conflicting communication

My partner is having an operation on both his feet - booked in for Nov 30. Despite applying for pre authorsiation 3/4 weeks ago we are still not getting the full story as to what is covered. The anaesthetist has quoted R3,700.00 for 120 minutes - Discovery provided a quotation saying they will cover R400.00 which is completely ridiculous. I went onto Discovery's Facebook page with this complaint and they were quick to respond saying someone would contact us which they duly did, they then advised me that the anaesthetist has supp**** the incorrect codes so back we went. <br> The PA at the anaesthetist then got hold of Discovery last Monday, again on Wed and for a third time on Friday and was told verbally, on each occasion, that the amount quoted by Discovery was indeed incorrect and that it would be improved substantially, she was advised that we would receive a letter from Discovery confirming the exact amounts - that was on Wed last week and we have still not received notification - how can we go ahead with this without knowing what is covered!
