Terrible tracker service

I had a tracker system installed in my new car, as per insurance preference. The technician broke my Bluetooth speaker in the car, and tried to fix it with black glue/presstick. The tracker device itself keeps going off through my car's speakers every time it sends a signal. So you can pin point exactly where the device is installed.<br> <br> I phone Tracker Johannesburg several times and no one ever answered. Going through other lines to get service, a technician came to inspect my vehicle. He told me I have to buy a new Bluetooth speaker from my dealer, for which I've never been reimbursed, and he can't doe anything about the system making noise though my car speakers.<br> <br> I phone Johannesburg again and again, still no answer. I have e-mailed tracker and still waiting for a response.
