Lies and *********ness

I am completely annoyed by the situation at hand. I currently have DSTV and am not looking forward to any additional or to upgrade my package. Yesterday I received a lengthy call from one of the agents advising me that I am a loyal customer and they want to offer me a benefit. On the recorded line even though I on numerous occasions mentioned I do not want it she advised it is a free benefit and proceeded to tell me "are you not listening to me, I said it's free". Today I then receive a policy document with an additional premium that I am going to be paying. I do not want this service/benefit! I distinctly mentioned this yet it was forced upon me under false pretenses.this needs to be cancelled as soon as possible.
