South African Airways customer care out of duty?

Since January 2015 I'm trying to solve a problem with SAA costumer care by phone and by e-mail.<br> Until today it was not possible to reach a person at SAA who is really responsible for my complaint.<br> After some exchanges of e-mails the contact is interrupted from SAA without any information.<br> Several attempts from my side to reach somebody responsible by phone ended in dead lines after long time of waiting and connecting from one person to another.<br> Will it be possible to find somebody at SAA who is really taking care of a problem which was caused by SAA?<br> Is there an Obbudsman for SAA?
