Newly Installed Tracking Devices not functional.

Not even 2 weeks ago I installed Netstar tracking devices in both my wife and my car and noticed that the device showed offline on my vehicle. Reported the matter and indeed it was discovered device was not working and was told technician will be dispatched but the ETA will depend on workload techies have. I asked what would happen if I get hijacked while waiting for techies and no answer was given. I just checked status on my wifes car and also getting same status from the app i.e. '' No activity from the tracking device''. What did you install on our cars? Do you know the repercussions should we get hijacked or cars ****** cause of poor workmanship or inferior products? Sort this out ASAP or cancel both contracts.
