Poor service and malfunctioning devices!

My partner and I installed their tracking devices on our vehicles, from day day one we have been having issues with the devices. On the app the cars will show two different locations, whereas they are parked right out side our home. This raises a question of how accurate are their systems should we get highjacked? Second issue is with the carwatch function on the app, which at first we though was a great feature. The car watch feature is supposed to trigger an alert if a cars ignition is switched on while the function is on. But you will receive a call stating that they received an alert on one of the cars whereas the car is not been driven its just sitting out side. The issue with the car watch function continued to happen and we will call the customer service department and no one will be able to provide us with any assistance. we will simple be transferred from one department to the next keeping in mind we are the once who continuously call them. Every time you get transfer you need to constantly explain your issue to each person. Third issue - once their agents have asked for your details they will call you by another name and mentioned cars that are not registered on our profile, at first we though it was a simple mistake until we noticed that the issue continued to happen more than four times. Forth issue is with the agent's attitude, we have had the agents drop the call when we explain our frustrations with the tracker and the service. The last agent to drop the call was a lady by the name Moeder.
