Disgusting service ever

Im utterly disappointed with the service from this company. I had a tracker with till my car was in an accident and writeoff. I don't have a car now. I made contact with them telling them about my problem and to cancel. They just wrote any email telling me things that don't make sense that either the next owner takes over from me or i continue to pay when i reply asking for clarity on this no one came back to me. How do i know who's gonna buy a car that is somewhere in a storage somewhere writtenoff by my insurance? How do i pay for a tracker i dont use? Did i invite the accident to my car?Did i choose to be car-less? Why would they handle my query in this disgusting manner. Where is their sense of customer service?Very disappointed.
