Refund and Reopening of case IOD

I'm really disappointed in the service provided by RMA, due to outstanding refund and re opening of a case which involves an injury I had at work and RMA was the company dealing with my IOD claim. On the matter of the refund consultant RMA and was told to forward all invoices,proof of payment as well my banking details which I did so and my first claim was paid out. On the second claim which involves Radiology, Dr. Consultantation and injection by the treating Dr. they only paid my Radiology claim and not the Dr. of an amount of R1 803.63 which they claim they need Dr. report which with the first claim none of that was required. The Radiology claim was paid. I've sent them all relevant documents including the Dr. recommendations as well treatment plan which was supposed to be done by now since the Dr. referred me to the physiothe****** for 6 to 10 sessions to determine the way forward with my injury. All of the attempts has fallen on deaf ears, this matter dates back now 27/09/2022 till todate the matter is not being re opened even doing and sending the relevant documents and reports to them.
