DSTV Cancellation PROBLEMS

I phoned approximately a month ago to ensure I get my dstv cancelled in time before I move.(Where I can't use DSTV at all) Was told that I should phone back at the end of the month. Phoned again today only to be informed that they can't find the call on the system and will only be able to cancel my DSTV in a months time. This is absolutely ridiculous as I will now be paying for something I can't use at all!! Only one day in the month I could phone to cancel?? (but already phoned once in advance to avoid exactly this situation!)Seriously something fishy. They have an obligation to cancel as per my request.
