Difficulties cancelling a month-to-month contract

<p>I have had a Telkom Mobile month-to-month contract for a number of months. In 2015 I requested that it be migrated to a month-to-month SIM-only SmartBroadband 1000GB, which was done. </p> <p> </p> <p>Recently I got FTTH (through Telkom no less) and want to cancel the contract, which costs me R1000 a month. On 5 December I submitted the cancellation forms and was told it would be 21 working days. It is now 13 January (25 working days) and it is still not cancelled. The call centre have told me, over various calls:</p> <p>1) It is still active</p> <p>2) It is still active but a 24 month contract and I'm only in month 13 now (????)</p> <p>3) It is set to prepaid (which is definitely not true)</p> <p>4) It is still being cancelled</p> <p> </p> <p>I gave my 30 day notice, I want this contract cancelled NOW. I do not want to pay a cent extra. </p>
