Why won't MTN just cancel your subscription ??!!!

I have done everyhting that MTN has asked me to do to cancel a sim subscription that was in my opinion cancelled almost 2 years ago now. I have waited on the MTN 808 call number for ages trying to reach a human who eventually told me that it would automatically be cancelled because I got hold of her. <br> Then i emailed retentions as well several times to get confirmation that it was cancelled, but only a stupid auto response came back to me and said someone would be in touch in 3 business days, who obviously never did. <br> Now I am checking my bank statements and still seeing the payment come off for R100 again this month....i am so frustrated with his company. I don't know what else to do to stop the this payment from coming off. It's been 2 nearly 2 years now! <br> <br> The payment is coming off my business account. The number I am trying to close is ***<br> <br> I have ref numbers : *** (#***)
