Receiving statements even after they told me my tracker is not active

<p>I have a tracking device installed through insurance in may 2014, I cancelled my insurance late 2014 and I was told that I am in a 24 months contract therefore I cannot cancel the contract. I then continued to pay directly to altech nestart. One day I decided to call netstar to test my device and I was told that its no longer active. after +-6 month netstar not debiting my account, in 2016 sept a debit order went through my acc, I then reversed it because I knew I was not owing them. in OCT and NOV same thing happened. I Then decided to call netstar to ask the what was happening and they told me my account was not cnancelled hence they atempted to debit my account. I then asked that they cancel it. it was cancelled and a cancellation letter was sent to me. I have now received a statement and an SMS "After atempts to contact you regarding your arrears Netstart account. you have failed to settle arrears balance of R319.04. please be advised that if you fail to contact ITCBA on ********** 497 to settle before 48hrs your information will be listed within relevant credit bureau and your service might be effected in the case of emergency". now Netstar wants to list my name for what?</p>
