Life Groenkloof Hospital Refund Process is worst

I have been waiting for refund almost a month from Life Greonkloof Hospital, its a 3 digit amount I already sending all the refund documents they needed from email since 2 October 2025, but the reply from Trevenia Seymore (Credit Controller) always asking the document that i already sending (they ask confirmation bank letter, i did send again and they ask to fill consent refund, i did send again then after few days they asking confirmation bank letter again) that make me fell that their services is bad and not professional. They supposed to archive the file when they receive it. When I call them, they always asking when you sending the document, it doesn't make sense, they supposed to be have marked all the document on the system, its looks like they didn't do their job. they also doesn't give me the detail on process.

Hospital giving the over amount quotation and must be settled full amount on that time, if i didn't settled full amount, the patient from ER will not move to ICU.
