Beyond Useless service

So it obvious Tracker "cares" more about roping consumers into contract with little to no regard for service: Emailed them the failure of a tracking device, even the description of the vehicle being incorrect and the primary contact. ABSOLUTELY no response......finally called retention's, escalated the matter and got one call back where they would make an appointment to resolve the issue with the device. STILL NO APPOINTMENT!!! So I've told them to cancel, because lets be real, they obviously cant or wont fix the problem and want me to pay an early cancellation penalty....... how "blurred" is that? I want me to pay for a service that doesnt work and pay because I want to cancel a service that doesnt work so I dont have to continue paying for something that doesnt work!!!! Your call centres are pathetic, your turnaround times to respond to customers is pathetic and the fact you dont even reply to the emails even more pathetic......not to mention if my car did get ******, yo lot wouldnt be able to find it!
