Non payment of in hospital claims

My husband was hospitalized from 30/10/2022- 01/12/2022. Sizwe did not update the auth so most service providers were left unpaid, i contacted them via call every month atleast 4 times a months to reprocess the bills, eventually in may 2023 i emailed them and finally received an email that the bills have been processed and payment will be made, however the Lancet bill was sent for reprocessing yet again, i owe lancet over 50k i emailed so many times, called so many times and all they want to do is reprocess, then ask me for ref numbers or they cant do anything, how many times does 1 bill have to go for reprocessing???? Im getting calls daily for payment, its been 8 months, why is sizwe finding it so hard to pay this 1 bill. If anyone has the email address for the medical aid ombudsman please share.
