Disconnection due to incorrect billing

Viewing was disconnected because of "We've stopped your DStv as you've not paid. To reconnect, pay R268.84 using ref no.***0. Once paid, we'll reconnect you. To pay: payat.io/dstv/***0." On enquiry I get informed it's still insurance I asked them to cancel on 17 January. Apparently they incorrectly billed in December and I continued to pay the same R904 for this. I can not be inconvenienced due to their error. About the insurance cancellation they said the insurance will contact me. Unfortunately the insurance was never made a condition for owning and viewing Dstv. It is a standalone that consumers choose to have upon being informed. Dstv must pay the price for incorrect billing which has been their worst nightmare since time immemorial.
