DStv masking my so called Netflix account

DStv will not allow me to cancel my Netflix account that I don’t even have access to. When I do request a cancellation with the company, they say that it should be done manually. I don’t understand the difficulty in them doing it from their computer system or from their offices. This is such an inconvenience to a customer. Now I’m stuck paying for a Netflix account that I don’t even have access to. I don’t even have Netflix on my billing account until a few days before my payment is due. Speak about transparency
