Defective unit

If there was an option for a zero rating I would giver Tracker Connect a zero rating. Their service is appalling, it's almost a month now without being able to monitor the movements of my vehicle due to a malfunctioning tracking device. I've called multiple times and they keep repeating the same thing which doesn't fix the problem, replacing the faulty unit seems to be the last resort, they're happy with performing trial an error while I'm not getting the service that I pay for. The call center staff is *********** and does not care about customer satisfaction.
