Tracker must stop this ****************

I had to cancel my subscription with tracker because the car is a write off. They told me about contract termination fee, to my surprise I never signed a contract with them. I called them a week ago for a follow up and I was told it is canceled but the debit order is still active. ;this explains why I was debited last month. How can I continue to pay for the services I'm no longer using. This is ****************, stop robbing us of our hard earned money. If I get a new car, I'll pay for 2 trackers? It doesn't make sense at all.
