Disappointed

I am very disappointed with Discovery medical aid. I submitted a claim exactly the same way as last month but I still have not received the money. Instead when I check my claims statement, they paid the money back to the doctor that I had already paid. I even had a chat with them on Monday and they said they will sort it out but it’s still not sorted out. Last month it took 2 days for them to process and pay the R800 into my account this time it’s been 2 weeks. How do you not see on the invoice that the member has paid the health care provider and is now claiming from you.
