Forced into a policy that I don't need

Last month I receive a call claiming DStv MultiChoice would like to say thank you for being a loyal customer for so many years. However there was a once off amount that I was required to pay in order to activate this "waiver" thing. To my surprise I have noticed that they have schedule a payment of +R300 to go off my account tomorrow. I was left with no choice but to stop the payment since they **** to me. I didn't know that it will cost me to be a loyal customer of MultiChoice. I just hope the payment does not go through and instead if you can leave me on the R129 ( Access package) that I have been paying as I am not interested in that waiver policy.
