Tracker ~ Beware

I have made numerous attempts to get the best customer service but to no avail. I am a new customer of tracker and my confidence in the product has been seriously bruised. Calls, Emails, app messaging and now my final attempt in getting the attention and service, through social media platforms. What I initially thought, was a fault in my car, I have replaced a battery as since the installation of the unit my battery dies overnight. I replaced 2 electrical components which turned out to be an unnecessary purchase. My car wud start and a few minutes later switches off and now I am totally not mobile, it was acknowledge that the unit has a fault. TWO Weeks ago whole driving the car switched off. Firstly I pressed the panic and to date I received no response. What would happen should my car be ******??? I made the 1st call and was told a technician would come through. Bearing in mind this is a serious emergency, no one came through. Called again and was told a QA technician would come through. Never happened. Few days later a normal technician was sent after the call center confirmed it would be QA technician. I've spoken to someone who may have been the team leader and he confirmed that the QA technician would arrive the same day, that was yesterday. Another day went by and still not even a call from anyone. This service is totally unacceptable. I cannot use my car due to this *********** product. Now that I want to cancel my tracker service and remove the unit as nobody should be waiting 2 weeks in an emergency situation. I must congratulate them though for debiting my account on time.
