Account Cancelled yet still being billed

Telkom, are you blind or stupid or both?<br> I cancelled my Telkom/hellkom/mekhom mobile account with you beginning of November, And I told you that I was stopping your debit order at my bank. Why do I still get a bill from you for Sim and Connection when All I took on your **** network was a sim card?<br> I did not Even take a device those 2 years ago.<br> I am sure by now, after 2 years that your useless sim card is more than paid for.<br> *** is your problem?
