********l debit order

Dstv had deduct R1050 from my banking account via debit order without my consent. I do not have a debit order arrangement with them. When I they send me a sms last week about the debit , I contacted them on the 12 and 14 December . Their agents told me that there will be no debit order going off on the 17 Dec because I am on the cash payment option. However the debit did went off but I went to reverse it of which the bank charged me R40 bank fees for. Its the second time its happening this year. So my bank charges is already R80. I send a email to *** but only got a automated response with reference number ***. I also complaint at the customer care on Facebook . Still waiting on their response. However I am going to report them to the ombudsman for Goods and Service . What gave them the right to institute a debit order on my residential account without my consent. Its ********l. For the past few days they had caused my headachs , unnecessary stress and expenses. They can check my account. I do not have a contract regarding a debit order with DSTV. . MR Uys
