DSTV unauthorised debits

DSTV have for two months in a row debit my bank account in spite of me cancelling my subscription. after the first month when my account was debited i took the matter up on live chat, i was assured by the agent that me subscription was canceled, when my account was debit again this month i was informed that account had been reconnected - I did NOT request this - the agent Seitiri Michael Moloi processed my cancellation again - i informed him that i was copying our correspondence and wanted written confirmation which he did email (ENQUIRY REFERENCE NUMBER : ***0). He has since emailed me on two occasions to say he is still waiting for the approval of my request for the reimbur*****t of 2 unauthorised debit amounts - he has since escalated the request because he has had zero feedback from the finance
