Price lock nightmare

I agreed to a 24 months price lock contract on the 21st of September 2020 but subsequently changed my mind, I phoned multichoice contact centre on the 22nd requesting cancellation and was advised to send an SMS to to 36488 with text cancel and the team would call me back. I sent out an email on the same day requesting cancellation to ***. I received numerous phone calls during the week for installation arrangements to which adviced that i have cencelled the request and would not be requiring the decoder. Multichoice delivered the decoder even though I expressed I'm no longer interested, I phoned call centre the same day - ref number ***-I11 arranging for cancellation and collection of decoder. I don't have the explora with me as it has been collected by the courier company arranged but my account is being debited. call cntre agents have proved to be not helpful as i have phoned so many times without any resolution. account has been handed to TCR for collection but there's no sense n paying for what I don's have. you concluded this contract without receiving any FICA documents from me. please resolve this issue as its causing unnecessary frustrations.
