No service & technical call back

My Netstar is faulty, which is a problem. I phone customer service, no one answers. On the 5th call, it is answered. I ask please for assistance as my tracking device is not functioning properly. They promise to have a technician call me. 2 weeks later I phone customer service again. On the 3rd call someone answers and after my long explanation again, the agent says a technician will phone me. That was 3 hours ago. I'm going to look for another tracking company, this is ridiculous.
