Refusal to cover covid testing

I'm reposting my review since my query hasn't been resolved despite promises to call me back a few weeks ago. My covid test claim was rejected because I wasn't referred by a GP. I used the online risk assessment tool on the discovery website as all doctors were closed on 25th Dec, as well as the Discovery call centre. I also tried the virtual consultation on the discovery site but nobody was available. According to the online risk assessment tool I was considered high risk & recommended to go for testing. I tested positive & paid for the test in cash. Discovery then rejected my claim. Discovery was unreachable on the 25th, 26th & 27th of December & i needed testing urgently as I was very sick. How can you not cover my covid test???!
