Total Frustration Dealing With Fedhealth - Feedback non existent.

( Hospital Auth : 58124 ) I was admitted to hospital as an emergency on 13 May 2021, which then led to a procedure being done in theater. Mediclinic Worcester app**** for authority and the stent that was approved was not available so a different stent was used. Fedhealth paid for the stent that was originally approved on the auth. Then Mediclinic re-submitted the claim for the different, more expensive, stent used. I contacted the Auth. department as on checking with Mediclinic the extra was not paid and they ensured me that the approval was signed off by a medical adviser and a care manager and that payment for the difference would follow. This never took place and then I realised that I would have to contact Mediclinic on a continuous basis to see if payment was received. I have contacted Fedhealth auth. department on various occasions to find out why payment had not been done. On 06/07 they put me onto Client Services who had to action the payment, the consultant escalated it to an accessor (***) and advised me that I should have feedback between 3 and 5 days. No feedback was received and now Mediclinic has sent me a final demand and said that Fedhealth said it would not be paid. I called client services again today 13/07 and now it has been escalated to a team leader with (***). I feel that this matter is just going around in circles and nobody seems to be able to sort this matter out. It is totally frustrating as you cannot get past frontline staff and then nobody gives you feedback.
