installation of devise

I am so frustrated with car track. The poor service is shocking to say the least. I have spent the whole day calling their client services and technical team and I'm being taken from pillar to post. The installation was scheduled in September 2020, but it was only installed in 29 May 2021. A day after installation the car lost power. then my windows and indicators started malfunctioning. Eventually the car stopped in the middle of the road. After numerous attempts to get a technician to come and check the installation, I was advised that he would arrive at 11h00, I called a number of times only to be transferred from one person to the other. Eventually Tyrell Kalle managed to get a technician at 17H15 to come check the devise. The technician was unpleasant to say the least. He concluded that the fault is with my battery and not their devise. I waited the whole day only to be told that my battery needs to be replaced. I'm livid.
