Very bad service

I would like to terminate my account with DStv , because every month they bill me incorrectly, I have to run the whole month without DStv because of the wrong billing. I am on access and how are they expecting me to pay over three hundred?

They are not treating me well and I am not happy because I cannot always complain about same problem.

This is now worse, I wanted to pay today since it's the 7th but I cannot pay because I was not billed correctly.

I am seriously running out of my patience.
