Cancellation of DSTV

I called DSTV to cancel my subscription. I have previously had 2 account with DSTV. I had cancelled one DSTV account in Sep (2 month ago) and had no issues relating to date of cancellation mid month. I called them this morning (13/11/2105) and the consultant stated i cannot cancel this account. I am flabbergasted as to why the change in a month or two. DSTV is holding me ransom fro soemthing I cannot afford. I have been a loyal subscriber for years and paid my account in time every month. This is not in good faith to the consumer.
