Car track poor service

We have registered with the cartracker and paid the amount, after paying the amount, 2 weeks back they send us a link and we couldn't see where the car is at but it only showed the nearest place which doesn't make sense....we did inform them but they didn't make things right...we not happy with their service so which means we pay for nothing. We no longer interested in their car tracker and we told them, they said they want cancelation fee but we never benefit from them. It's useless and a waste of time to go on with them. please help us ASAP. We want better service but not with them. We want them to remove their device from our car with emmediate effect cause we scared we gonna lose our car because of their poor service. Please help us.
