no help

I was admitted to Life Wilgers hospital from the 22.4.2024 till the 25.4.2024. I was discharged before 12 pm but the hospital charged me for overstaying. Now I owe the hospital an amount that the medical aid did not pay. I have send this to in an email to the case manager and are completely ignored, not even the standard "we have received your request". So how must I sort this out? Also the medical aid has paid for those days except R1,843.88 of the R17,726.32 on the 9.6.2024 but the case manager says they have not been paid! Life Wilgers is a good hospital but their accounts department is a mess
