On air tv

I have calling to stop the debit order since I canceled my subscription and product collected within 7 days which is 3 months ago. But every 2 a month they debit my account. I keep calling and an agent tells me my subscription is cancelled. Dstv and showmax pls intervene they using your brands to hook customers into taking this on air tv. They are so desperate to ***** our hard earned money. Service providers don't be alarmed when we reject your online products we scared of being **** to and ****** money from. Our bank accounts. On air don't even bother to call or reply. Just useless.
