Discovery refusing to pay what is due by them

<p>I was admitted to hospital in Centurion last November, and spent 3 days there. I went through a procedure that I had gone through before, a few years ago. However, this time around, I received a bill from the hospital in January, telling me that Discovery did not settle the bill in full. I called Discovery, and they claimed that the procedure had a co-payment, something that did not happen the first time I had the procedure, and something I was not notified of beforehand. This was on Friday when I spoke to them, 27/01/17. They promised to get back to me on Monday 30/01/17. It is wednesday, going on thursday, and I still have not heard from them. After being with them loyally for ten years, and with the fortune I am paying for the medical aid, I am still expected to pay my own medical bills? This is unbecoming, being treated like this. They don't even have the decency to call me back.</p>
