DSTV ********* deductions

Dstv is charging me netflix subscription costs even though i have my own netflix account and it is debiting directly from my bank account. when i called to query this i am informed by the consultant that if you just press the netflix button on the remote, you will be charged. i disagreed with the consultant because you have to register and log into netflix in order to view anything on netflix. when i requested a refund i am informed that it cannot be done. i am really not happy with this and can see why they are loosing customers.
