hospitl insuance without my consent

On the 20 January I went to Jet to close my account as I haven't been using it since September and I have paid it so I have only been paying instalment of R189.00 when I get at jet they tell me I owe R1340.00. I asked them why I owe this much money when I haven't bought clothes and I have been paying instalment they say it for hospital insurance which I specifically said I don't want when the consultant told me about but now I have hospital insurance that I specifically said I don't want. I called edcon call centre on they have been saying they will fix it but they haven't done anything. I have been calling them for full 3 weeks and they always say they will call after 48 hours and they never do they don't give me how far they are with my case. its so unfair to be done like this without my consent now I have to pay for something I said I don't want,im so angry frustrated to what they are doing I don't this account I want to close it. I hate edcon with a passion for the customer care and the call centre its so unfair. the consultant I spoke to in customer service is skhumbuzo he hanged up the phone when I wanted to know how far they are with this case im angry so much
