Unresponsive Makro

Does anyone know how to contact Makro? They seem to be completely unresponsive. Tsepo from the call centre promised to escalate and respond. Nothing. 3 emails to *** and 1 forwarded to ***. Nothing. Being so unresponsive is a good way to lose customers. I used to be a Makro fan but things seem to have deteriorated in a big way.
