MTN no response, follow up or accountability

It has been another week of not hearing back from MTN. I posted a complaint three weeks back and got a call from an agent. We had an email exchange, and I was told that the complaint required feedback from the store in question- this was a week ago. I have sent follow up emails this week and have had no response. <br> I require that all contact is via email as I do not have a device (it is sitting in a safe at the MTN the glen store). I have continued to pay my contract fees throughout this period, regardless of the fact that I do not have a working device. <br> The entire ordeal has been 3 months of back and forth and changing consultants
