Dstv is *****ing from me

I'm using dstv ultra, I noticed on 24th December that it says I've subscribed to Netflix and they've added the R200 Netflix to my dstv account. I contact dstv service center same time to tell them I didn't subscribe, they told me to call Netflix to cancel I called Netflix, Netflix told me I don't have an account with them they don't have account with my email, I must call dstv to reverse charges, I called dstv they still insist I have an account with Netflix I must quiry it with them whilst this money is been debted from my dstv account. They refusing to remove R200 for Netflix which Netflix has already confirmed with me that my details don't appear on their side they can't cancel something that is not there. Meaning someone at dstv has Netflix account that is paid by me.
