Admed Guard risk co payment claim

I am desperately trying to get my co payment back from Admed, prior to admission to St Georges Hospital on the 14th of April, I personally contacted Admed to advise them that I needed to make a co payment of R5720 at the hospital, the amount advised by my medical aid provider, Bankmed. The call centre Agent at Admed Guard Risk advised me that i will be able to claim R5000 back as an annual payment. I submitted the claim online which reflected the co payment and was then advised that the file format is not correct, although this account came directly from St George's Life Accounts Department. After numerous hours on the phone to my medical aid and Admed I am still nowhere, yesterday I was on a conference call with Admed and Bankmed trying to obtain the initial authorisation letter for the hospital stay on the 14th of April, however the co payment amount is not reflected on the admission letter. The lady from Admed Guard Risk also then asked me to submit my claim statement from the medical aid to her listing the itemised billing, I do not see why my medical information needs to be disclosed to Admed and why the full account is any concern of yours, I paid the co payment on the 14th of April, its shown on the statement uploaded on your online claims site and I am now expecting a refund. This is the first time i have ever claimed under this policy and unfortunately it has not been a pleasant experience.
