DEBIT Order does not mean ***** my money

More than double the subscriptions was taken by debit order. I queried when the SMS was sent and was advised that the amount was incorrect (their own stuff up) and it will be resolved before the debit goes off.....BUT that never happened. I followed up and still awaiting final feedback. Interim feedback seems that the agent is *********** and further the issue was on the side of the DSTV Accredited installer that cancelled and reactivated my service multiple times incorrectly. So can you do the right thing and credit my account.....useless service
