unwanted insurance

Good day<br> I have an acc with truworths last year i paid it up and did not use the acc for a few months then by dec month i went and bought clothes my instalment was 310 january i paid the 310 and then i get a call from truworths to say im in arrears of 90 for the funeral cover from hollard which i then explained that i never agreed to any insurance i was told to call hollard which i did and they(hollard) told me that they will fix the matter and get back to me within 7days which never happened i tried to explain to truworth but im being told that its my problem and that i have to fix it my self i feel that im being treated unfair by truworths and hollard i have a bad credit record because truworths gave hollard my detailes and now its my responsibility to make sure that the insurance is cancelled and hollard is not prepared to cancel the policy in the mean time my arreas are pilling up
