Worst Service Ever by Telkom

So my contract ended in May 2020 of which I asked Telkom not to renew it and cancel it instead. 8 months later and Telkom still debits my account every month and when I try to call them they keep saying they will investigate and get back to me which they have NEVER done. I went to their store and the store people said they can’t help me and would need to call the call center. I resorted to canceling the debit order but now they charging me a debit order admission fee of R240 everytime. I’ve been trying to fix this for 8 months now but it’s not helping. Even their Twitter person is of no help. They refuse to give me the reference number when I call cos apparently the call is the reference. I’ve asked them to listen to my calls and send me the calls so I can prove to them that I’ve been calling but still nothing. So what is the point of them saying they are recording the calls if they won’t make these calls available on times like these.
