Incompetence to do their job

I closed my account beginning 2016 and after numerous attempts to make sure my account is closed, Telkom is still trying to take money from my account without my permission and to make matters worse they have put it on my credit ratings, that is bad now thanks to their incompetence to just close an account. Its more that a year and a half now.. REALLY!!! This is my 3rd review on Hello Peter about the same issue.. maybe 3rd time lucky. Fix my credit report and stop trying to take my money.. I did everything from my side to cancel my account the right way, I went to the store.. I sent emails with the cancelation from attached.. I phoned telkom.. ( all costing me more money) but your side is not coming to the party.
