Telkom

Hi, I had canceled a telkom sim contract on the 26 September 2018,it's now December 2018 I receive a debit order for the past 3 months fee.I have been to 2 telkom branches and I have received zero assistance from them,apparently it's the last debit order.This makes no sense as to why am I billed 3 months later for a cancellation that took place in September 2018. I feel ****** and cheated by telkom as this is not the first time they trying their luck.I need this to come to an end.In September 2018 I was debited R600,now I receive another debit but this time it's R330,claimed to be a cancellation fee. This is utter nonsense.I need this to come to an end.I'm not utlising thier services,It frustrates me because every consultant I speak to says yes mam iter canceled,and we can tell there's zero usage on the sim.basically never been used but why still debit me.

Is there any way I can put an end to this *******?
