Discovery is finding every excuse not to pay my claim

I submitted a claim 16 March (***) under the above Ref number, however For the past 4 weeks I have been given the run around on outstanding information on the Dr's invoice.

Whenever I call I am told the invoice is incorrect, we do a conference call with the Dr's office and the Dr's office amends the invoice accordingly based on the call with the agent , but when I submit the amended invoice I am told again information is missing.

I am honestly not happy with the service that I am getting. The invoice should have all the information they need to process my claim, I paid cash R53780 to the Dr for the procedure and Discovery has to reimburse me on this authorization number ***1.
