Poor Customer Service

I called the Defy Appliances service call centre on ********** 339. I requested to have one of their technicians come out to fix my stove, I told them that I'm in Durban, to which they told me that a technician would call me to make an appointment. When their Durban technician calls me, he tells me that he does not attend to customers that are in my area (New Germany). I ask the technician whether there is another technician who can attend to me in my area, and he says "NO, there isn't another technician" and he says he will call the Defy head office on my behalf and a few days later and I still haven't been contacted and my stove is still not attended to.. I waited 4 business days for a technician to call me and when he eventually does call me he tells me that he cant assist me because I'm not in his area. Please can Defy sort this matter out, because this is unacceptable. My name is Mnotho Khuluse and my contact number is ********** 832
