Faulty device and awful customer service

I've had frequent problems with the tracking device, and once again the tracking isn't accurate. Once again I called Netstar, struggled to hear the ****led conversation by the agent (as usual), just to be transferred 4 times and holding till I couldn't hold anymore. The problem still exists. There is also no other way to contact Netstar other than by phone. The only reason they got a 2 is because if and when the device actually works it works well. Other than that, I won't recommend this company. The service is terrible
