Disgusting customer service from Multichoice

I have been getting a bad service for the past 6 months and I called in to cancel the contract even before it started because they were not delivering their appliance when I called I was told I can’t cancel the contract they need to come collect the decoder first now 2 weeks later I am being debited for something that am not using when I call Multichoice I am being told I have to pay cancellation fees for a contract I did not even begin to use please pay back my money and cancel the account
