Telkom not canceling Service

Cancelled all services for *** on 23/062015. After holding for almost a combined 3 hours, I was informed that I must send a cancellation letter on letterhead and copy of i.d to stocst@telkom. Received an email from Telkom SMBS Retention acknowledgement, without any reference. I send the cancellation documents again and then a third time every time receiving a mail back from the Telkom SMBS Retention acknowledgement. 30/072015 service still not cancelled and still getting almost R2000 account for line I am not using. <br> Been holding for cancellations for exactly 46 minutes now.
