Vodacom Insurance ****.

I have been a client since 2014 and this year they have shown me flames. I have tried numerous times to cancel my cellphone insurance and they have not taken my request into consideration. My ITC report even shows that I am 30 days in arrears for not paying, and how that came about I wouldn't know. I will not pay R1 160 for a phone and insurance that I have been trying to cancel with no assistance whatsoever. I will keep on reversing the money and paying the amount I signed up for until that insurance cancels automatically or until someone actually come forth to assist me with the cancellation. How can I be in arrears for insurance that I have never signed up for and that I have not even benefited from?
