For the past 4 days I've been trying to get someone from Netstar to assist regarding me trying to track my vehicles location on their App. I've made numerous calls to their customer service centre but none of them were able to assist. On Tuesday afternoon a consultant said their supervisor will call me back but as of this morning no one has bothered to call. I'm always being told that they're experiencing technical issues. If their IT departments can't get their system up and running, fire them get someone who knows what they are doing. The app works for a while and then nothing, especially in the afternoon. Very bad service from Netstar and their customer services.
