Telkom won't cancel account!

I've been trying to cancel my old Telkom line and adsl ***) since January 2015 but each month Telkom happily goes on deducting money from my account.<br> <br> I sold my house and left the country at the end of January but still I can't get Telkom to cancel this account.<br> I visited a branch before I left to cancel the account, I subsequently have emailed every address I can find on their useless website (with no email reply to date), I have called them once a month for four months now. And each time I call them (from overseas!) I am on hold for MORE.THAN.AN.HOUR!. I then speak to various well-meaning but ultimately inept people who assure me that the account will now be cancelled, I get given a reference number, and the next month another deduction goes off!!! Rinse and repeat.<br> <br> How can this be legal? How can I get Telkom to actually cancel my account as they keep promising?<br>
