Bull**** Service from NETSTAR

My tracker hasn’t been working for about 3 weeks, it last logged on the 16/06/19, I’ve contacted Netstar 3 times so far but the only response I get is that there’s no signal and they will log a querie and will give me feedback, I’m still waiting for feedback........ I’ve been driving around with my tracker not working in fear that if something does happen my vehicle will not be found and the only response that Netstar will give is that they got no signal, what’s the point having a panic button if it will do nothing???? If I’m hijacked, who will know???? If I’m missing how will my family know where my vehicle is???? I need an urgent response because I am sick and tired of this nonsense.......
