Froud of netstar tracking

Good day would like to report them as ***** they deduct installments recently on my father's account and he is in Australia the past 3 years and no vehicle in south Africa for the past 3 years. Netstar start deduction 4 months back on his account with no authority. I phoned them to cancel this but they can't help me due to it is in my father's name but he did not approve this. As I do have signing rights to Handel his business in south Africa they still refuse to cancel this deduction that they just decided to deduct with no authority.
