Claim not getting processed, despite phone calls and emails

Since early October I have tried to claim for a brace supp**** to my wife while in hospital after an injury.

I paid cash for the brace.

My claim has not been processed a number of times. For different reasons.

I submitted a receipt and the prescription. This was not processed, One receipt with the doctors name was requested. This was supp****.

I have had many phone calls and emails to Discovery to try and resolve the matter.

I lodged a written complaint to Discovery . This resulted in two phone calls from Discovery on the 9th Dec with a commitment to sort it out from the second caller.

I would really appreciate it if one person at Discovery would assist me until this claim is processed

Thank you
