Cancellation fee

On the 11th of September 2017 my car got involved in an accident unfortunately it got burnt so i call chase because the whole night they didn't call me to notify me if there's something wrong with the device they but in my car. What I expected is that when the device goes off after it was burnt then their system have to pick it up and at least call me but no now when i call them they are telling me i must pay cancellation free. The car is burnt so must I continue to pay for a car that is burnt? What will they be tracking? They failed to even pick up their device was off honestly their system is useless I wouldn't recommend it to anyone. It means that if you are sleeping and your car got ****** you wont even get a call from them untill you call them so thats the point of having their device if you still have to do monitoring yourself? I can't pay a cancellation fee for a car that is burnt and their device didn't even notify them that it is faulty at the time or shows ot is off.
