Discovery takes forever, systems needs to be updated

I am so upset now. I have submitted special claims forms on 14/01/2023 as instructed by discovery, I submitted it online on their website. I phoned now to find out how far the process is, as they say it takes between 2 to 5 business days. I gave the reference number, and they don't pick up anything on the system. This is not the first time I struggle with them so much regarding claims. I have arranged with the doctors payments will be made by today or tomorrow, now I had to resend it by email. Now it is going to take twice as long, I should be receiving payments by today already so I can pay the doctors. This is really unexceptable, I am disgusted really. It should have been all done by now.
