Cancellation Issues

I emailed through my cancellation request on the 5/7/2017. I received a automatic email saying a telkom representative would contact me in the next few days. My account is still active, I haven't been contacted and I don't even live in that province anymore. I went to the telkom store and they informed me that the only way to cancel is by emailing the cancellation email address. I sent a second email on the 27/7/2017. And the same automatic email followed. Till date I have no response!!!
