TRACKER TERRIBLE AFTER SERVICE

So i have had Tracker for about 3 years on my car. It seems it has not been working for the last 3 years and i am partially to blame as i am told we are meant to call in every six months to test. But the fact that they are wanting to charge me a call out fee to have it replaced/fixed when i have been paying them for a service for 3 years that did not work. <br> Also the fact that i had insurance and they were still charging me full price was even further annoying from their side. <br> So i requested cancellation of a non working product. I was then told that i must give a notice period of cancellation. I wait the period and get an sms on the day stating \Tracker attempted to contact you wrt your cancellation query. Kindly contact retentions department. We will continue to Bill you for services."<br> <br> Call them at 8h15 am and get told they are opened from 8am - 5pm. and the call cuts. """
