Compcare - unreasonable delayed payment of claim

Patient was admitted to hospital and subsequently passed away. We are still awaiting payment for 4&5 July 2024 account. Upon query 22 August 2024 call ref ***7 I am told the account has gone for reprocessing. 10 September- claim still with assessors - call ref Tumi ***September- claim still being worked on Gugu call ref ***0. This is completely unacceptable!! How much more must be worked on when the authorisation was and is correct!!
