Can't wait for my contract to end

Terrible customer service. They kept calling me to find out about my unit even though I kept telling them my car was involved in an accident. They took forever to re-install the units in my new vehicle. They asked me to get them an address on my car that was written off and taken by the insurance. They say that I need to phone in every 3 months for them to check if my units are working. I believe they should be phoning clients to check if THEIR product is functioning or not.
