Cartrack when will you fix your issue or leave me alone?

I am beyond frustrated with Cartrack. It seems the only way I can get them to hear me out is when I write a review here. I have been struggling with Cartrack since they installed a camera tracker on my bran new car. I’m not sure what their technician did to the car but it messed up the alarm system. He came back the day after to fix this and admitted that he couldn’t and would disconnect the alarm while escalating to his manager to come and fix. They never did. What’s worse is that because of this, I’ve had to be without a car for 2 days while it was back at the dealership to fix. They’ve asked that Cartrack removes their tracker as it’s not compatible with the car Meanwhile, since their system was disconnected, I’m not sure why they are calling me daily to collect money from me. For what? In all these calls, I keep explaining the bad experience I’ve received from them - to no avail. The next day, I get calls, emails and even my WhatsApp is flooded with their messages. Chasing money instead of service!
