Tracker removed, still receiving statements

<p>My car was sold in November 2016, as per my previous inusrer they requested that the vehicle is to be fitted with a tracker from Altech Netstar, which the insurer will be repsonsible for. I bought a new car in November 2016 and also got new insurance from a different insurance company, I notified Altech Netstar that the current vehicle is being sold and that the tracker needs to be removed as I will not be making use of it any longer, the tracker was removed as I requested but now they are still sending me statements and billing me for the tracker every month after I informed them telephonically and via email (as they requested after numerous phone calls) that the tracker was removed and the insurance has been cancelled. I want this issue to be resolved ASAP as I have been waiting since November, I expect Altech Netstar to send me a paid up letter confirming that there is no outstanding balance and that the aco**** is closed as this will be reflecting negatively on my payment profile.</p> <p> </p>
