call logged but unattended

<p> a case was logged on the 18/03/17 to cancel my contract, but never resolved till this day but my bank acc is debited every month. and i dont have the device or sim with me. i decided to reverse the debit evry month and they'll change the ref no and debit again few days later. i'm so disgusted of the service i'm getting from Telkom. how long does it take to cancel the contract. and how do they collect payments for inactive line. </p> <p>i just want this settled so that i can move on. and never ever try to be their client again.</p>
