What Nando's customer care?

Approximately a week ago I called the Nando's customer care line to lodge a complaint regarding the Bryanston Nando's drive through. No joy there. In response to a hellopeter post recently, a lady by the name of Mzaki called me from customer care and left a message on my voice mail on Wednesday and Thursday (I was out of the country). I called her back today (Friday). The interaction was lacking to say the least. She couldn't recall the fact that she had left two messages for me, was not au fait with the complaint and simply said that she would escalate it to the branch...what I was told two weeks ago. The customer care line seems to be managed as poorly as the Nando's Bryanston drive through.
