Bad service from Bonitas Medical Aid

Bonitas member !!!!!!!!!!!!! I had a procedure done at Sunninghill hospital on the 05/04/2018 for stents to be inserted in my left leg. I had received authorisation from Bonitas for this procedure, which was duly performed on the date. After receiving my account only 6 months later from Sunninghill Hospital, did i find out that Bonitas paid for the Stents but did not pay for the Balloons - as this is one procedure and the one cannot be done without the other i contacted Bonitas to query this. After numerous calls to Bonitas ( +- 24 Reference numbers can be supp**** ) and speaking to different agents every time, who then start from the beginning again, and been told that there was no authorisation requested for the Balloons. During 3 of these reference numbers i got told by - 1) 13/11/2018 - Vusi - Case manager this account would be settled in full - " NO PAYMENT " 2) Ref no - BON ********** 2 - Thabo - Account would be paid in full and correspondence would be sent to me via email - " NO EMAIL OR PAYMENT " 3) 27/11/2018 Thabiso - said that he had spoken to Thabo ( Case manager ) while i was on the phone and confirmed that this account would be paid in full - " NO PAYMENT " I have also communicated with the case manager from Sunninghill Hospital on numerous occasions and she has emailed Bonitas all the relevant information - but still no joy from BONITAS , and Bonitas told me on they had not received any email from Sunninghill Hospital on the 30/10/2018 - This was resent on the 05/11/2018. This account has also been handed over to Sunninghill Hospital's attorneys for collection on the 29/10/2108 !!!!!!!!!!! On the 20/12/2108 i spoke to Lesego ( Ref no - 201218Q5DMWO ) and he said that he could also not understand why this has not been paid, and that he would take this up with the case manager Mpumi and phone me back - " NO RESULT OR PHONE CALL " Today i phoned and spoke to Nqobani and asked to speak to Lesego, he told me Lesego would phone me back - " NO PHONE CALL " It is not a case of i am on a cheap medical package with BONITAS - i was on the 2nd best medical with BONITAS - and as from the beginning of 2019 i am on the best medical package with BONITAS MEDICAL AID> My question is - why has half the operation been paid for and the other half not paid when i had got an authorisation number from Bonitas ????????? And why must i try and sort out NAPPI codes etc. when it is Bonitas Medical Aids duty t do this ?????????? THIS IS ******* SERVICE FROM BONITAS MEDICAL AID !!!!!!!!!!!!!!!!!!!!!
