Disgraceful Neglect to assist patient

Disgraceful Neglect to assist patient. During my hospital stay in Netcare Linmed Hosital (emergency admittance) I was treated by Dr Singh. She did not submit the claim with the correct procedure codes to the medical scheme (Discovery Health) and as such the hospital is now sending me an Invoice to pay as her treatment cannot be linked to the authorization, and the authorization we obtained was never updated after she insisted to extend my stay in hospital. Despite numerous attempts to contact Dr Singh and ask her kindly for her assistance to please send the correct procedure code to the medical scheme - I get told that I cannot speak to her and must leave a message. I have left more than I can count. Dr Singh: if you see this - PLEASE, just 5 minutes of your time can resolve this matter. (Mr Hechter - 4-8 July 2024 Medical Ward). If you could please just send the correct code to Discovery Health and update them on the correct discharge date, then Discovery Health can process and pay the claim from my hospital benefits.
