Worst tracker...doesn't work or track

Worst company ever. ****** tracker wasn't tracking correctly n eventually stopped. I made request and calla and only to be told, drive 5km and reboot. With what petrol n I dd that eventually they rescheduled for a technician to come and was made to sit home n wait for them and nothing. They insisted it working but nothing, drive 5km n check like what he'll. Still no problem has been solved. 8 days with no tracker. Worst company to ever choose from. Don't ever take risk with yr cars about this company
