CAN'T CANCEL A LINE

Have proof of cancelling our Telkom line on 1 March 2016 giving 30 days notice. Completed the correct forms and received a confirmation email from the cancellation dept. Again repeated the process on the 15 March and 30 March as the line was not cancelled. Called and spoke to Linda on *** (Supervisor) on 1 April 2016 as we moved out the house and he guaranteed within 24 hours this would be sorted. To date have made over 30 calls, been in to a Telkom office and still this line is not cancelled. It is pending cancellation only from 6 April and therefore will only be cancelled on 6 May even though I can prove we cancelled the line timeously as per Telkom terms and conditions. We are now told we have to wait until the line is cancelled on the 6 May and lodge a dispute to be re-imbursed. This is not good enough Telkom. I have proof the line and ADSL lines were cancelled correctly but you WILL NOT assist. No one calls back. Why must we wait. Sort this out now.
