Discovery Health Unpaid Claim Again!!!

This is like the 3rd time this is happening to me. I recently submitted a claim for payment from my medical Aid savings but the claim was not paid. I reached out to the call centre who said that the agent who processed the claim, said no ICD10 code provided however when opening the claim, the new agent confirmed that all was in order and could not understand how this claim was rejected for “no ICD10 Code” and she than said she spoke to a supervisor and said that they would reprocess the claim and I would be paid by Friday the 10th May 2024. This has not happened as promised and now I need to call them again to go through this whole process. Why is it so painful and time consuming dealing with discovery health when submitting claims. Rather disappointing and I think it really is time to look at other health insurance alternatives.
