Disgusting behaviour by Netcare

I was recently hospitalised for an emergency incident at Netcare Rosebank. They decided to keep me overnight for observation. They put me in a ward specifically for ER patients while they awaited a covid test. They got my test result next morning which was negative. I was released before they placed me in a 'general' ward. In their infinite widsom they invoiced me as being in a 'private ward' (which I was not). My medical aid is rejecting payment for a 'private ward'. Netcare is dragging their heels in correcting the code on my invoice. Now they have issued ma a letter threatening my credit rating and threatening legal action!!!! Can you believe this??? This is their fault completely and trying to get them to fix the problem has so far proved impossible. Disgusting, greedy, grabby, ***********, blood-sucking attitude from Netcare!
