MTN - Bad Bad bad service as always!

MTN - Bad Bad bad service as always! I have been battling for two months now to cancel a data account with MTN. They simply just don't do it. Probably because they want to keep making money from me with their excessively expensive data package which I want canceled immediately. My request was forwarded to their retentions department on 1 September already under reference *** (and ***). Several conversations and reference numbers further I still have no reaction!!! I spoke to Gwen, Nandi Xabanisa, Nombuleli Qamata and a host of others, not counting all of the Service Champions who promised that I will be helped. Pathetic! They still send emails asking for confirmation info, even though I already submitted it. This is a clever way of making money from vulnerable customer that don't have control over them levying funds from their accounts. Very divisive tactics! I fully expect an apology and to be refunded fir all debit order that went through since my request was ignored! Come on MTN stop the lousy service!!!!!
