Kingsway Hospital Accounts Problem

I took my son to the emergency department at Kingway Hospital on a Sunday in late November (possibly 23 Nov 2014). I was on Discovery medical aid and was asked to pay in R148 at the time of consult to which I had no problem. Months went by I got posted a 7 day notice from the hospital dated 7 Feb 2015 which I only picked up on 13 Feb from the post office stating that I owe R193.21 otherwise I face legal action. For the record I received no email, no SMS , no phone call let alone any mail stating that there was a shortfall but I am now threatened with legal action. I have no problem paying the money but it would be nice to get a breakdown of the account showing how the shortfall came about. I spoke to Theo on 16 Feb and he told me that his SAP system is down and he will call me when the system is up an running again. I spoke to Stella Cumlasagasen again today 19 Feb and again she told me her SAP system is down since monday and she cannot check on my account to check if sms or mail was sent out to me. What angers me is that she told me that I should have checked my medical aid statement and picked up that there was a shortfall and paid them irrespective of them sending me an account
