Discovery Health Customer Service Declining

I called Discovery in March 2024 to load my primary GP for my Chronic, the service consultant entered the incorrect doctor, when i went to my GP in September my bill was shortpaid. I again called discovery October to ask them to review the account, and was told that they will have to first pull up my conversation from March. Having not gotten a response since my request I again called Discovery in December as was told yes the service consultant made an error in March and my account will be resubmitted for payment. I called again today and was told to hold whilst the lady was checking with her supervisor/manager, I held on For more than 23 minutes in total and eventually cut the call. Discovery Health Service Consultants need to surely have better training, so that customers dont have to call 5 Times to sort out an issue that could have been rectified after one call.
