A colossal nightmare with Discovery Part 2

In April i had an issue regarding a claim from my maternity benefit. The issue was resolved only after i contacted Hello Peter and again i have to go this route due to *********** people working at Discovery. When that issue was resolved i asked Tevin who assisted me if the next scan will be covered, he advised it will not be but because i have funds available in my maternity benefit, i can claim and i will be refunded. I went for the scan on the 5th of June. Received the email We have received and assessed your latest claim(s) -MailRef#***#-8th June 2020. The email states that R677. 70 would be paid to the specialist Heidi Nolan on the 10th,its approved and the R1057. 30 will not be paid,which as advised i could claim back from my maternity benefit, there is funds available and i all ready paid that in cash to the specialists. I then sent the invoice and proof of payment - ***. I called Discovery to confirm if the proof was received and explained the claim,as i dealt with this issue before. I spoke to Yurisha Naidoo-9th June 2020. Yurisha also confirmed yes i have funds available in my maternity benefit to process the claim. Yurisha called me back the next day to inform me that the R677. 70 is going to be paid to me, i advised her it should not be paid to me, as i am claiming the R1057. 30, and the R677. 70 should be paid to Heidi Nolan the specialist. Yurisha said she understood she will get back to the claims dept, and will then call me back, she never did.Then on the 13th June-R677. 70 got paid to me. I called back spoke to Kiso, ref number for the call - ***. Kiso does not know anything and makes up things as he goes along,he kept on telling me i did not have authorization when i told him that because im pregnant i dont need authorization and also i have a ref number of a call where i was i told i dont need authorization as long as my gynae refers me,he said he does not want it, he then placed me on hold for more than 20min or so, came back said he was going to resubmit the claim and he will call me back the next Tuesday or Wednesday, he never called back. On the 15th June-R179. 88 got paid to me again. So in total R857,56 got paid to me not the R1057.30. And now i got an email from Heidi Nolan on the 21st June, wanting payment as the medical aid did not settle the account.So it seems the initial payment that was approved to her was reversed , why only the heavens know, when i explicitly told Yurisha the specialists must be paid. I want the specialist to be paid and the rest of my claim aswell. I honestly dont know why this is such hassle. Everyone working at Discovery seems to make up things as they go along, the customer service is really the worst that i have experienced.
