Unable to CANCEL DSTV subscription TODAY

Have recently moved house. No longer watching tv in empty house and therefore want to cancel DSTV subscription. Called in yesterday (21 July 2015) to cancel. Was told, you can only cancel at the end of the 30 day cycle, and my billing date is the 1st of every month, so only able to cancel on the 1st August 2015. So in essence, the EMPTY house is now able to view PREMIUM DSTV for another 9 days!!!! I was told on the 21st the issue would be escalated and that I would be contacted during the course of THAT day. YA RIGHT! Called again today, was told the same b*ll****. However, other complainers also trying to cancel have had their subscription disconnected and received a refund for the remaining days of the month. WHAT IS THE PROBLEM HERE, why can this not happen? I'm told I am on a 30 day OPTION, however, DSTV has NO OTHER OPTION, only month-to-month contracts. Its not as if you pay per day!!!! THIS IS HOW THEY ***** FROM PEOPLE, FORCING PAYMENT FOR NON-VIEWING! I want the subscription CANCELLED IMMEDIATELY and pro rata refund IS DUE !!!!! THIS IS ****************! 30 day cycle MY @SS !!!
