Useless company

On Wednesday 02/05/2018 I received an email from tracker stating that the Tracker Skytrax unit in my car has not detected vehicle movement recently and I have to call to resolve the matter. I use my car everyday for work and a day never goes by without me driving my car. When i called tracker I was told that my car has not made any movement for a month now "according to their system", I told them that they are putting my life and vehicle in danger by not picking this up in a shorter time. The agent then told me that it was my responsibility to check if my tracker device was working as if i work at tracker, I'm the customer my responsibility is to pay. I want to cancel my contract with them and move to another company where I am going to get a better service and not worry about my device not working but was told there would be a cancelling fee!!!!!! If my car was ****** and the device picked up last movements from a month ago who was going to replace my car??? I want this contract cancelled without a cancellation fee.
