Debited me incorrectly after cancellation

On the 28th Oct 15 called into call centre and CANCELLED my DSTV subscription because we were emigrating. No problem cancelled contract and subscription as of 28th Nov 15. On 28th Dec 15 get debited R361.50 for DSTV. When I called them they advised yes our system AUTOMATICALLY connected you on the 28th Nov 15 for half the month and we charged you. Okay so your mistake DSTV can you reverse the debit order from my account.. No sorry if we refund you then it will take up to 60 DAYS to get refunded .W e suggest you as the consumer who has now been inconvienced by DSTV to go back to your bank and cancel our debit order . This will be quicker for all the cc agent advised. My complaint is three fold one how does a system automatically connect you after you advised them to disconnect you? Two who gives DSTV the right to just debit my account without even asking or confirming? Three now me as the consumer is inconvienced and I msut now do phoning around to reverse the debit order and they cannot refund me because of their error. Very poor customer service with no apologies or even attempts to try and help you rectify the situation. Been a customer for 10 years plus!!!
