MTN are bunch of ******* and ****mers

MTN is worst ever service ever experienced and still experiencing their ****. I app**** Aug for a ,month to month subscription LTE with Free router paid full Aug amount and my pro-rata for Sept. But I only needed the service for a month for I was moving and cancel it at begin of Sept , so went to Secunda MTN store an gave the router back that they ask for and cancel my service, didn't care about the pro-rata that I lost. But now they are so ******** they are renewing my subscription every month without my consent, I do not even own any MTN product or use service, so now they charging me every month by debt order for service I don't use and be honest they can see I am not using their service it will show on data usage I use? So how do they do it? They are ****mers, and now want to report me at Credit bureau. I have evidence of all the emails they are renewing my service and did not follow up on my cancelation. Going show lawyers this ******** acts they doing , just look at their reviews on Hello Peter, they are the worst and should get sued
