Telkom Contract Cancellation

Good Day Please assist me with the cancellation of the 1GB Smart Internet for ********** 787..

I have an existing Telkom contract that has ended in December 2017, I have been to Telkom stores and they gave me a form to send to their cancellations department. I have sent the forms and have been waiting for weeks to receive confirmation, when I contacted Telkom last week the consulted informed me that they will log a call for my request but i have seen not received any communication from them.

I went as far as sending communication to their escalations department and have not been assisted with this request. The sim card has lost network activity and I will be paying for a service I can no longer use.
