Medihelp not responding to any communication.

I was admitted to Netcare Montana hospital on 1 July '25. I had full Authorization with the exception of a few items on the authorization letter that my Dr removed from my billing. I had a R5000 co-payment which i paid as per agreement. I now sit with a R9000+ outstanding Hospital account that Medihelp did not cover stating the hospital over charged. This has now become a back and forth between hospital and Medihelp, with no response from Medihelp after Hospital sent out required information. *** does not respond to any queries. In the mean time my account is getting in arrears and is affecting my credit score and trust worthy payer.
