one year later and debit order not cancelled!!

I cancelled my Telkom internet last year December but the debit order continued to come off my account.<br> After various un helpful telecoms and internet interactions with Telkom help line,<br> They said the paper work had been lost between Alberton branch and the cancelation department.<br> So I filled in another cancellation form in June, stating what had happened. Since then I called 081180 number on 26 August an operator by the name of Kwazi said he had sorted it out / the debit order was cancelled and I would be refunded the moneys paid from December 2014. On 5 November I called again and spoke to Tindi. after been put on hold for 20min, she told me the case was closed and I had to resubmit the cancellation form. I did so and was sent yet another case number, however 2 amounts came off my account again last week I sent 2 emails last month - but no reply!!! This is now the third complaint on HelloPeter and all I get is the same electronic response \Thank you for making contact with us. Please be assured that this matter has been escalated to the relevant department and feedback will follow."NO ACTION!! Telkom are not a company who respond. I Just received another invoice!"""
