Receptionist not answering calls and makes promises that she does not keep

<div>My mother and father went to Wigeheuwel hospital where a blood test was done and they tested positive for covid, but the doctor submitted a incorrect code and the medical aid refuses to pay. My father who is 73 years old drove twice to the hospital to ask ***** to submit the correct code. she keeps on promising that she will do it, but has never done it. ***** keeps on promising that she will get the doctor to fix the code for Lancet to the medical, but is not sending my father proof and she does not answer her phone and is never available.</div>
