MRI Claim : System issue

I submitted a claim for MRI Scan and after 3 days it shows that I need to pay the full amount. I already paid a Co payment of R3850 and got pre authentication for the rest. So I called discovery and they said the system is not working properly and she did an escalation. So now I have to wait another 3 days for an outcome. This is unfair as I need to claim back my co payment from my gap cover. This exact thing happened back in Feb with my dependent. Now more than a month later your system is still not fixed.
