MULTICHOICE RFUSING TO CANCEL MY CONTRACTS

I have a contract with multichoice where they gave me a wifi router and explorer decoder on compact package. I no longer want the contract. I asked multichoice dstv to cancel the contract and they said I need to pay R3168 and after that I will own the router and decoder and the contract will be canceled. I paid that amount and still the contract was not canceled. I called them again to enquire and they said that the money I paid was juts for outstanding fees(which I did not understand) and they said I still need to pay R4299 to have the contract canceled, because I want nothing to do with multichoice anymore I paid the R4299 ( in a space of 5 days after having paid the R3168) I then received a call from them saying they are canceling the contracts but to my surprise I receieve an sms saying I have app**** and paid for a package upgrade AFTER HAVING TOLD THEM THAT I WANT ALL CONTRACTS INCLUDING ANY SUBSCRIPTION OF ANY KIND IN MY NAME WITH MULTICHOICE CANCELED!!! I then called multichoice and explained what happened, they checked and said no contract have been canceled and I still have active services with them. I also asked them to update my ITC which they have not done after paying over R7000 to have my contracts and any subscriptions canceled with them. Please help
