Poor service, I'm paying for two devices however i told them the other car was sold,the technician was supposed to go and remove the device and install it to my new car,hower they did they own thing they install a new device promising me they will go and remove the old device,they never went there now i can still monitor the old car i can still see the movement is that safe for a big company to be so careless? is it safe for a new driver not knowing i can see all the movements,the technicians must be hold liable of the costs too as they were aware of my situation but they choose to fool me around,i have a recording of them speaking with the guy from the dealership stating that they will come and uninstall the device but they never went,bcs they dnt care now i have to pay for double cars..
