DSTV is taking money from my account.

My debit order for a price lock contract, went off at the wrong value. Do you think I can get someone to sort this out for me? 3 People at Multichoice have now escalated the query, because no one can see my details on their system. How can they just take my money, without an email or sms or a note. The debit order is supposed to be fixed, but a different value went off?
