DCC. Cancellation of Decoder Insurance

I have e mailed Multichouce DCC on numerous occasions to cancel my Decoder Insurance, no feedback no correspondence, still the Insurance exsists. I requested the Insurance ti be cancelled as frim the 1st of December 2017 but as to date nothing has been done. Call centeres just turn a blind eye, misrible and irritated to assist, i will not waste my money phoning call centres just to be rude at, we as customers contribute to each workers salary, but we get treated like *******. Without us the customer, there wont be a Multichoice.This is un exceptable, you are fast in collecting subscription money from us or disconnect if its a few days late, but when it comes to assist us we sit in the back seat, i want the Insurance CANCELLED as i have requested over and over again. I have done more than my part in trying to communicate to you, get your act together and attend to my request. Sick and tired of this nonsense.
