Unacceptable and *********** Service

I submitted a complaint via the Discovery platform, to reach them directly. This was with regards to claims that was rejected because of codes that "was not on the invoice". The codes was in the same place as all other claims that I submitted previously. So a lady phoned me on Monday to say that she can see the codes displayed correctly, the claims will be paid out. The claims are still not paid out. This is unacceptable. They are not doing me a favour, I pay them for a service. Which at this stage I'm not receiving.
