Claim for a vitality check which did not happen

I recently joined Discovery Medical Aid and I am on a 3 month waiting period. Yesterday, I received a notification that a claim was filed by Discovery Life for a vitality check done by Southern RX Pharmacy on the 8 September 2020. This was obviously not a valid claim as I did not have the vitality check. My wife and I queried with Discovery Health but they transferred us to a lady by the name of Merle at Discovery Life, citing that they submitted the claim so they should sort it out. Well Merle politely claimed that she could not help as the information she had on the screen was the same as what we had. According to her, the nurse who handled the life policy application tests, forgot to submit the HIV test. When we explained that our policy was in effect for over a year, she basically told us to sort it out with the nurse. Why do I have to fix the problem of a ********** claim on my medical aid when I alert Discovery to it? I was not even on medical aid over a year ago, when the health check for the policy was done. So disappointed!
