MTN: Horrible customer service

I have been waiting for almost 5 weeks now to get feedback from the MTN HVRC repairs with regards to my warranty claim. I call them everyday to get the status of all the escalations with regards to my device and everyday I get the same story, "We have not received feedback". I wrote a review here on Hello Peter and MTN responded to say they have escalated to the same department HVRC repairs that I have been getting poor service from, they said they will call me within 48 hours but nobody called. On the 21st of Dec 2018 I spoke to one of the supervisors by the name of Kabelo who also promised to call me back and give me feedback but never did. Not only is MTN doesn't care about customer service but their people also make false promises. Festive season is not an excuse for incompetence, every business works on skeleton staff during festive but it's not reason to provide horrible customer service. The worst part is all this delay was caused by an MTN employee who made a mistake when booking in my device and all MTN does is blame their own for making a mistake. I am tired of waiting, all I want is my device back. MTN refers to themselves as the Boza network but in all honesty they are not, they don't care about their customers.
