Worsed experience ever!! I took out my unit with them from my car I dont even have the car anymore. They still calling me for monthly collection fees and cancellation fee? DOES IT EVEN MAKE SENSE TO COLLECT CANCELLATION FEE AND MONTHLY AT SAME TIME!!!!!!!!!!!!also I have requested the recording where they explain pre cancellation fee penalty I AM STILL Waiting yet they took it upon themselves to list me on ITC. I will not let this rest. If i do not get responded to i will take it further, Been requesting recording....... i will pay should it confirm agreement of pre cancellation fee untill then I DO NOT OWE CARTRACK a damn cent.!!!!!!!!!!1
