Disconnect service via website not working.

<p>This is the 2nd time I have requested a disconnection of my service via the DSTV website but it doesn't work.</p> <p>I requested a disconnect for 27th March, and even phoned before the date to confirm which I was assured of but I have not been disconnected, now I have been billed for a service that I don't use, must undo this.</p> <p> </p>
