Contravention of Consumer Protection Act

When checking why DStv price went up over the last two months out of the blue, I was told by the customer care agent that they automatically signed up customers for Disney+ after "three months free" despite us NEVER having used it. I then asked which three months were free and what basis was used to sign us up and received the response "September, October and... we just signed you up". I then asked if she was aware that is in contravention of the Consumer Protection Act and she confidently said "Yes". Despite asking for a full refund (as stipulated in s31 of the Consumer Protection Act) and a call from management, they refunded only a portion for November and have not called back.
